I cleaned a care home Wednesday night. I got the call from the owner a few week ago saying the quote I had given was ok and to come and do the job. I said I hadn't quoted at the care home, her reply was 'I have your card here and you came round last week to give a quote'. Anyway I went round and she did have my card, I don't know how, and a quote from a company with a similar name (I saw the price quoted).
I turned the charm on :-) and offered a quote, funnily I came in £10 under what she had already been quoted and I now have them signed up to a maintenance plan paid monthly :-)
