[John comes back after the self check out at the supermarket refuses to accept his credit card]

Sherlock: You took your time.

John: Yeah, I didn't get the shopping.

Sherlock: What? Why not?

John: Because I had a row... in the shop... with a chip and pin machine!

Sherlock: You had a row with a machine?

John: Sort of. It sat there and I shouted abuse at it.  - The Blind Banker, Sherlock
