I'm about 2 weeks behind at the mo. On wednesday had a lady tell me how late i was. Normally (like others have said on this thread) they moan when you turn up and say that your early. Anyway, this lady asked if I could clean them again as close to xmas as poss. The 23rd or 24th she asked as she has family coming. If she thinks I'm doing her windows on Sunday 24th she can think again.
Most of my customers are ok with the fact that we get put back by the weather. I'm lucky as I can earn a few bucks labouring for me mate if it is a rainy day or 2.
