I was once in a bar and a friend of mine REALLY fancied a Waiter outside the opposite bar. He sent him a message (via a waiter at our bar) to ask if the boy would go home with him.
The answer came back Ï think my body is worth five thousand Baht".
Now, I know this boy works for much less.
I took it to mean that he didn't fancy my friend and was politely saying NO to him without hurting his feelings.
