Things that haven't caught on in Korea

You're wasting your outrage.
SPQROFLOLBBQ eats outrage for breakfast (alongside his fried pork and soju, I suspect)!

A long time ago I decided I wasn't going to do/partake in three
things in Korea:

-spitting
-cigarettes
-soju

Obesity.
Bumper stickers degrading other political parties.
Loud car speakers that shake anyone within 50 yards.

Just taking the piss (although I do actually think you eat outrage for breakfast).
Everybody needs to draw a line somewhere, and yours seems imminently reasonable.

fixing things seems to have never caught on.
owning your own tools and doing it yourself seems to be lost here.  Everything is delivered to your door and assembled after a 50 dollar charge. 70 if you dont have an elevator.  if you get a flat tire its much easier to just call the insurance and a guy will be out within 30 minutes.  Changing your own oil is basically non existant. most electrical products that people buy are either heavily covered with after service, or are disgarded when something breaks, The trash pile in front of large upscale buildings is a treasure trove of goodies, discarded by people who think themselves too good to fix something. I get that its a throw away society here, but it might do the environment good if we could repair our own things.
Get some tools.

Clearly you don't shop in Costco or has something changed since I left back in the day? Have they gotten rid of the extra large-arse style shopping trolleys?

Absolutely, when I told my Korean friends and co-teachers how I could fix cars, do electrical, tiling etc, they stared at me as if I was from Mars. I taught myself to fix cars when I got my first car and ended up with a pretty neat little car servicing part time business with over 200 regular customers.

This one seems designed to catch the attention of D.Mart

Is this a current menu?  Looks like they brought some things back?  Big disappointment last time I went.

Joining Costco is now on my bucket list.

Aim higher. hahahahaha

So good...savs in a bun with sauce. Joining Costco is now on my bucket list.

You haven't lived till you've tried that free onion ketchup and mustard salad!
That said you don't actually eat it. You just pile as much as you can onto to a plate and leave it there because that shows how classy you are by not actually having to eat it.

Why you sticking me in a bun? ;)

They have nachos now, and that terrible hamburger is gone.  They had a pretty good chicken salsa wrap for a while but they seem to be gone.  The calzone is back.

You know, there are two ways to respond to people of different cultures doing things differently or not being aware.

For example, in Korea, one of my newbie friends went to the "self" area of a BBQ restaurant and got glopping amounts of banchan and put some, shall we say, odd combinations together and when told about the whole leaf wrap thing, proceeded to make a leafy near-burrito. Now, the Koreans there could point and laugh and use it as a source of ridicule of others or they could just shrug and move on. I don't think my friend or any of us would have appreciated the ridicule (although some might be fine with it and laugh along!)

I think the better angels of our nature should go for the latter rather than the former. BUT, if you're fine with it being done to you in a derisive fashion, then laugh away at others.

Pretty sure it's only you that finds it derisive but whateves but I still find it quite amusing watching groups of Korean people ordering large amounts of food but rarely eating more than half of it. Call it a cultural quirk if you will but there is not need to take offense. My wife still finds a lot of my behaviour in Australia quite amusing, but I just play it up and laugh along. For instance it drives her crazy watching me walk around bare footed in the back yard and then walking into the house without putting on slippers. 

...or walking to the shops in your budgie smugglers 

Nah, that's a bridge too far. It took my wife about 18 months before she allowed me to wear track suit pants outside the house though. She thought they were far too informal.

FYI, you don't need membership at the food court.

"Hahahaha look at me deliberately tracking dirt and filth into the house and making you clean up after it and watching you stress about it! Hilarious!"

Look we all have our things with our SOs and things we laugh at or tease about, but dude...this just doesn't come across well at all. Maybe this is something you could forego the playful teasing and wear some slippers and spare her some cleaning. Is this really something worth being a mild nuisance over?

You do realise that in other countries people don't always take off their shoes and put on slippers when entering their home without freaking out about dirt and disrespecting Korean culture don't you? It happens all the time in Australia.  Perhaps you should encounter some other cultures occasionally and get out of your bubble. It could be quite liberating for you. Imagine not having to worry about having holes in your socks.

In some countries, when visitors are expected, the TABLE must be clean! Wipe all bits onto the floor if needed; in other countries, when visitors are expected, clean the FLOOR! I have experienced this table vs. floor priority first hand in several countries, years after first hearing about it: Anthropology 101.
