I have a waiting list and I make sure the customers know it. Its the most wonderful thing that has happened to me as a window cleaner.
The customers see me in a new light, no longer "Oh its just Vince the window cleaner."
They don't mess me about because they know that I can pick and choose and whats more "I ain't Bovvered !"
Sacking you by text is just a lack of respect. It probably not the whole story though. Some household bills have gone up by 25% and everybody is feeling the pinch
