Mathematics and tips

At a local hotel today I overheard the following conversation while waiting to order a coffee.

"Great that's £2.00 please for the coffee."

"I have a discount card."

"That's 15% off then."

"Can you take it as a tip? You know, take the 15% off for the discount but add it back as tip for yourself?"

"Yeah, no problem. That's £2.30 please!"

Oooops!
