Had one of those this very day.
Said she'd looked our number up on the internet, rang us, had us round and was given a quote.
Later she rang up and booked in. When we got there.....
It wasn't us that had given the quote. Her take was to blame us for not ringing her back when she had made the appointment to point out it wasn't us who had done the quote. Of course the client is never wrong
Anyway, we measured up and it came in at c£180. We knew the quote she had been given was for £120.
The strange thing was that she had cleared the rooms. Also she was going away on holiday tomorrow and the carpets had to be nice for her daughter's wedding a week on Sunday.
She said we could do the job for £120.
We politely declined and left.
(If she'd asked nicely we'd have done all the carpets for £120 and simply not done the small amount of upholstery which she also wanted doing but which didn't really look as if it needed doing at all. But as there was no hint of compromise on her side I think on balance we could have been letting ourselves in for a hard time if we had done any work for her.)
Her loss I think.
