Eating in front of people who are not eating something... eating in company when the others are eating too is not that bad.

What is wrong with today's kids if This kinda stuff is "embarrassing"? This is life, you should get one. Strangers don't care about you as much as you think they do.

"Embarrassing" is too strong of a word for most of these. I would say uncomfortable would fit better.

Awkward more than embarrassing - embarrassing is having an itchy nose hair and having someone walk into the room while you're trying to move it.

weird form of social anxiety in protestant countries,never noted this behaviour in catholic italy spain argentina or brazil..,ppl are so weird every social interaction is accompanied by weird stares and tensity ,specially noticeable in elevators,it gets better the further south of europe u go in italy nobody cares if you enter the elevator they say in germany they look at you as if you invaded their bathroom while they bath

....plugging up your friend's toilet (because you've been constipated) during their bar miztvah and there's a line of people waiting to use it.........oy vey!
