Taking a star off here, because I was yelled at by the cleaning lady there.
Apparently it was an unforgivable sin to stack my used plate on top of another used plate, because it will make the upper plate "dirty at the bottom".
How the if-you-see-kay does that even make sense? Don't you wash the bottom of your plates?
Well, it made me feel homesick again, because in China, waiters yell at you! ;)
P.S.: Food was still so darn good.
