You guys struggle with the concept of free refills and putting ice in drinks.
Free refills I will give you though I get looked at oddly whenever I appear stateside (one for the queue, one for walking to the table, one for the meal, one for the waiting for everybody else to finish their meal, one for the road, possibly another for the road and another to walk out with, if they have multiple flavours of things I am interested in then all bets are off) but ice in simple soft drinks* always strikes me as odd- it comes out practically at freezing and will not last long enough to get above 10 degrees C so what is the problem unless you enjoy chewing on ice? A few places here are catching onto the idea of refills though (mainly American shops that come over mind you) so it could be good.
*beer on the other hand. I think I will dismiss it as, microbrews aside, what passes for US domestic beer is all pisswater anyway.
Back on topic I am surprised Russia got in on that list.
