Had a customer, nice old girl, come out and said, "well it's the new year, let's talk money!" I laughed, she has said to be loads of times, "let me know when price going up," "you put your prices up yet" "is it still same price".. Anyway, I only charge her £10 but she always give me £12.. It's a big house, not many windows, only 2 tops.. So I said yeah, we will go up to £12 then.. She laughed and said "what you mean put it up to £12" and walked back into the house.. Came out with £14.. Said I always like to give you £2 extra.. If only all customers were like this!
