I hate working in the rain, as do most of my customers, so for me it's not really a problem. There are a few who don't mind, so I can belt away on those regardless.
I had a call from one this afternoon, asking me to call later in the day. She phones me every 1-2 weeks, and lives 2 minutes from me. I got there at about 5:15, it was dark and hammering down. I suggested going back tomorrow, but she was happier for me to do the windows then and there than I was!
It certainly takes all sorts!
