to me, it seems that americans cannot go anywhere without holding some sort of beverage or another in their hands. im not sure how much they drink of it, however. they always seem pretty full, is it more of an accessory than a drink? americans tend to forget it everywhere, as soon as they put it down, somehere, anywhere really, they forget all about it. and thus you see cups with all sorts of drinks standing around everywhere. literally. on the street, in the subway, on some shelf in a shop... one time a guy even forgot his in the overhead compartment in the airplane. until i told him to please take it...
just this sunday we had lunch at some tiny tiny bakery in boston, there were only 6 seats or so. but we managed to get 2. the sandwich and croissant were sooooo good! on top of that, the coffee was yum too. but it came in..... paper cups. my delicious macchiato, and only a horrible wooden stirrer to enjoy the milk foam... :( buuuuhhh! why do even the nicest of places serve coffee in paper cups? (the bread at least was on a real plate).
ah well... above you see a bubble tea, somewhere in chinatown. i tried a sip of bubble tea only once, and thought it was disgusting... so i do understand someone left that behind... :) (just click the link if you want to know what wikipedia has to say about bubble tea!)
