I know its blowing 70 mph winds out there :

but I have to look forwards

This is my second week wfp and so far all results are good. and the reason for this was preperation work, for the past six months, I read topic after topic, and took note of what was written.
I spent extra time cleaning the tops of the frames changed my detergent, and just two changes made, while I was trad, payed dividends when I finally changed over to wfp.
Now I am convinced that changing over to wfp in the winter is better and the reasons are as stated by a few guy's, on here, if there are any mistakes in your work, the chances the customer seeing it is reduced, as its normally dark when they get home, and by the time the summer comes you should be a little more experienced and up to speed.
Also I found using wfp over the past couple of weeks, there hasn't been any complaints with regards to the ground being left wet, thanks to the wet weather, so come the summer the customer has already seen the results of better cleaning.
But my question is, do you normally get any problems in the summer, with customers moaning that your leaving every were wet, or if there sat at there patio's, and say not today were having a patio lunch?
just want to look a head and be prepared with some good answers.
I know unless the reason is genuine, and they say not today they will be bid farewell.
