In today's hotel, I had a quandary. Preparing to wash my hands in the toilet, I saw two signs above two sinks. One said, "Only for customers of X restaurant" and the other said "Only for customers of Y restaurant". With X and Y both being Chinese names, I didn't know which restaurant I had been eating in. Not wanting to break the rules, I just rubbed my hands on my trousers and left with my head down!
