The point is, about working in rain, light drizzle etc is, I thought the same way as alot of new guys when I first started WCing. Now we clean domestic work in any weather, providing it's not really peeing it down. The reason is, we don't like getting soaked

Another thing I've found over the years is not to second guess my custies. It's a good idea not to try and see things from what you imagine they do. A good eyample of this would be my last big lesson from this forum. We have had 12 weeks of snow here in Boxheadland. Couldn't work with ladders, so was starting to get way behind on domestic work by the middle of January. Got the advice to do bottoms only or work with a trad ploe on the upsatirs.
I thought the custies wouldn't be happy about trad poling the upstairs. Second guessing them really. Did all our custies over a 6 week period. Lost none, no complaints. Enough said?
I would never consider for one second, sending them a letter to explain how I work. It's not being tough with them, it's just not worth the trouble trying to explain to some custies who have no idea about work, money, prices and costs etc, how you provide a service.
We all share the same custies, if you see what I mean. If a guy like me or Daz can run like we do, why can't other guys do the same. It's all down to attitude and how you are with your custies. Another example of attitude would be: If you have 400 custies and one comes out with "not today, it's raining", how would you react?
If you only have 50 custies and you get "not today, it's raining", how would you react then? Same custies, same problem.
Stop thinking they all think like you. A good way to test the water is, try cleaning 10 custies in light rain, see what happens. Not much damage can happen can it?
What I've found over the years is that more than half my custies aren't in when I clean them. So if it's rained during the clean, it could be dry and sunny when the get home. If we clean between showers and they come home to clean windows, how do they know it was raining as you cleaned them?
Most of our work is cashed up sometimes a week after cleaning, by that time they have forgot about the weather from when you cleaned them!
Don't let your biz get run by what YOU think THEY think.

Hope this makes sense,
