never had any letters, had loads of stupid reasons for cancelling or to skip this months clean.
think the best reason i had to cancel was when i was out collecting: customer says if you can afford a new car like that i dont want you to clean my windows.
best reason for skipping a months clean: was last week, started the front of a bungalow when customer comes out and says im half way thru a sandwhich! so cxan you leave it this month. joke is she then spent the next 20 mins eating it whilst talking to her gardener! as i was doing the other 8 bungalows around hers.
same day and same road - about 15 mins from that customer - customers says no! leave it this month i wanna do the insides first - i said i can do them for you, if not if the outsides are clean then it will be easier for u on the insides. customer just walked off
some people are proper fd up
