I had one about 10 years ago. It was a first clean, nice detached house in a small village. The owners also ran the post office next door.
Just before the second clean was due, I had a phone call from the lady asking me to cancel. I didn't ask why, but thanked her for letting me know, and left it at that.
When I was in her area I went into her shop to buy a choccy bar. As I was paying for it, the lady asked if I wanted to know why she had cancelled. I said she didn't have to explain herself, but she was at pains to tell me.
Apparently just after I had cleaned her windows she was burgled, losing cash and jewelry. I said I was sorry to hear that this had happened to her, and asked if she knew who may have been responsible, and when it had happened, and had she reported it to the police. She then said that she thought I might know something about it. I said that I didn't, but offered to go to the police to make a statement, and provide proof that I wasn't party to the crime. She then said that I may have told friends what she had in the house, who may then have burgled her. I then told her that I do not look through people's windows, as I have no interest in their possessions, neither would I tell anyone else if I did see anything. Moreover, anyone I may know who steals is no friend of mine.
At this point, her assistant, who was a long standing customer who knew me well, intervened and gave her boss a glowing character witness of me.
Tom Crowther, don't let this incident get to you. As we can see, many of us lowly window cleaners have been accused of stealing, but most of us have integrity, and so have nothing to worry about.
