This is something we just don't get here in the west. A really bad waiter is great for breaking tension between people meeting for the first time; bitching over the poor service can unite the entire table. And sometimes, after a few too many cocktails, things may get really exciting and devolve into fisticuffs.

But how could you possibly punch a little monkey?
