I used to work with another teacher who had been out in China for a while, and spoke pretty good Mandarin by the end of it. When he was first starting out and learning though, he went on a date with a Chinese woman (who spoke good English). He was trying his best to practice with his Mandarin in the restaurant, and asked the waiter for an extra plate. The waiter and his date both looked like they were trying hard not to laugh, but the waiter said “no problem, I’ll just bring it to you”.
He then thought “oh god, what did I actually ask for”, but his date laughed and refused to tell him, and said, wait and see.
The waiter than came back and presented a giant of a chef with a big grin on his face to him, and said “here he is”. Turned out he had asked for an “extra fat man”.
