I had a customer the other day query me using WFP when I've done it that way on her windows for years...
Her: My friends window cleaner gets into the corners better using a squeegee; can you do it that way?
Me: No, I use WFP, it's been fine for the last few years hasn’t it?
Her: Yes, but my friend said you can get into the corners better using a squeegee.
Me: That's not really true, I use WFP - squeegee for inside work only.
Her: Also, a lot of birds keep dying after you've been because they fly into the windows!
Me: That's because I do such a good job with WFP. See you in 8 weeks
Some customers! I think I might drop her, more hassle than its worth!
