You hit the nail bang on the head , any new window cleaners should remember that  the customer needs you more than you need them . I have ben turning work down in the past but now tell all new customers that I can clean your windows but , 
1, I have to be paid when I have finished .
2, If  they cant manage that they should look for another window cleaner.
3, If I have started to clean there windows and it starts to rain I will finish cleaning  them. 
So now when I get a new customer I retire a old call back on friday to be paid one
