So picked up a new customer today. Lady walked up as I was cleaning one up the road. Asked Ware the regular guy gone. As I'm subbing the work in this village I told her he's covering different area. OK she says can you do mine I'm on way out so will pay you now. Hands over £12. When I got over there there is only six windows. Rang old boss and he informed me she has never been his customer. So my question is should I tell her next time £12 is a bit mutch and knock a few quid off?. Or take the £ as she happy to pay. Also wonder if I'm going to piss off her windi if he comes back. Aparantly he's not been seen for a while.
