Hotel industry joke

One day I went to a hotel for dinner and ordered some dishes. Later, when I checked out, the waiter said, 26 1 yuan, count me in 260 yuan.

At that time, I suddenly realized and asked, what about 264 yuan?

He said it was also 260.

So I said loudly: Give me a bottle of coke, only three yuan. ...

I clearly saw the waiter's face twitching.
