Okay, so in Taiwan, everyone says "bu hao yisi" (poss. translatable as "it's embarrassing") when they want to say "excuse me" to someone to a) get their attention b) get them to do something/anything c) express how embarrassed they are (I'm assuming).
Here is a real conversation:
Me: I'd like a latte please.
Cashier: It's embarrassing, but the cost is $2.50.
So--today I found myself saying "bu hao yisi" in /English/ to a cashier in a coffee shop. (I had handed the (Cosi) cashier my (Starbucks) travel mug and asked her to put the coffee in there, saying I would pay for the larger size, since we didn't know how the Starbuckese size translated into Cosiese size. She was about to try it out in a paper cup first--*to be instantly thrown away*--before I managed to stop her.)
The End (?)
