Things non-Americans find weird about the U.S...

Things non-Americans find weird about the U.S.  These are curated from a Reddit post, and they are both interesting for their perspective, and entertaining to read through.  An example of the latter:

Choice. Buying a sandwich was utterly bewildering the first few times.

For example, in the UK a typical exchange between me and sandwich guy might go like this over the period of 30 seconds:

Me: “Can I have a ham sandwich please”
SG: “White or brown?”
Me: “Brown”
SG: “Any salad or sauces?”
Me: “Lettuce and mayo please”
SG: “Here you go. That’ll be £15 million, and your car and your house.”

Similar exchange in the US, over ten minutes:

Me: “Can I have a ham sandwich please”
SG: (over-enthusistically) “Sure thing, Sir! Which of these two thousand varieties of bread would you like today?” (None of which qualify as bread, but that’s another subject…)
Me: “Oh, er, not sure really. That one please”
SG: “Sure! That’s a multi-grained-crap-tasting-full-o-sugar-shit-fest-foot-long-sub-roll. Do you want enough ham to sink a battleship, or would you prefer just enough to make you shit like a bear for an entire week?”
Me: “Erm, I’ll go for merely enough to induce meat-sweats for 8 hours, thanks”
SG: “What kind of cheese are you after?”
Me: “What have you got?”
SG: “Montery Jack, Jack-o-Lantern, Jack of all Trades, Tastes of Jack Shit, Chilli-Jack, Rubbery-Jack and Jackie Chan.”
Me: “No Cheddar then. I’ll go for Monterey Jack”
SG: “Gherkins Pickles?”
Me: (confused and overwhelmed by all the choice) “Can I just have the sandwich now?”
SG: “Sure! I just need to know what else you want on it. Jalapenos?”
Me: (exasperated): “No, thanks but re…”
SG: “…Olives? Cucumber? Lettuce? Relish?”
Me: (eyes glazed over): “No, thank you, it’s fine as it is”
SG: “Toasted, roasted, basted? Mayo, coleslaw, salt or pepper?”
Me: “No, thank you, really, the sandwich is fine as it is, please can I have it now before I starve to death?”
SG: (confused) “Sure thing! Here you go. That’ll be $0.000000001 please”

Of course, a similar list might be made of things that Americans find weird when they visit overseas.  At the top of my list would be this one:

No matter what country I visit, the inhabitants, from infants to the elderly, can all tell with just a glance that I am an American.  I don't have to speak, gesture, or wave a flag – somehow they just know, even when I'm hundreds of feet away from them.
