Flat Tyres

[Rondy]

On his way home from work a man noticed his tyres were going flat. So he nipped into his local petrol station to inflate the tyres. After he'd done that the lady forecourt attendant asked for £2.
"What's that for? It seems a lot just to put some air in the tyres."
"Well that's inflation for you." She replied.

I don't know why he bothered, they were only flat at the bottom.
