I had one yesterday, the guy called me over from cross the street. I went over and gave him a quote after him walking me round the property. There was a small issue at the back with a DIY decking made with flat planks, with no groves in it, kind of like what wooden crates are made out of. Any way I said I couldn't use a ladder on it, but would use an extention pole instead. He then agreed to a four weekly clean and I asked him for some details: -
name: bla bla
flat no: bla bla
house no: bla bla
phone number: "no!"
Now I have had a one or two oldies being a little reluctant to give there number out before, so I wasn't really bothered I just went on to explain that we don't give out the number to anyone and only use it to make alternative arrangements if it happens to be bad weather.
the guy then said "I don't give fcku who you are, I don't give my number out to anyone"
"ok, well I cant add you to my list then"
"Fine just do them today then, and don't come back"
me "No, I think we will just leave it there" and walked.
Now I am really not too bothered about not having a number for a customer, I do have a few I don't have numbers for on file, but this guy was paranoid nutter, who obviously though of himself as a bit a hard man, and knew he was going to be trouble, so I just walked.
