well, I learned a leason yesterday.
last saturday I went to do a quote for an old lady. " my window cleaned has not bn about for four months, can you clean them."
No prob, I can fit you in Friday.
" that would be great"
Friday morning, get a call " oh he came today and asked if i still need him, so jst said yes, but I wanted to let you know so you don't waste your time coming round. thanks anyway"

so now I am thinking, as soon as they agree to the quote offer to do them there and then.
not all bad though, lost her, learned a lesson, and picked up 4 other jobs
