What I would do depends on a few different things:
1. My mood.
2. The customers size.
3. The customers temperament.
4. Have I anything hard and heavy to hand?
5. Is Wor Lass with me?
6. What witnesses are around?
7. How spiritual am I feeling?
8. Do I care at that moment about any subsequent police investigation?
The best case scenario is that I would do as requested, billed the guy, and not worry about it. The worst case scenario is that I would knock the living daylights out of the cheeky git!
