Just wondering, when the guys are there with their squeegees in hand do you hope they don't single you out while you are stopped at a red light?
Do you hope they do? If so, how much do you tip them if they do your window(s)…
How do you feel when they do the window(s) without having gained your consent?
I'm not for or against myself, but just wondering what others think…
Just shake your head at them, add a shake of the hand in a "stop" motion too, if needed. If they insist on doing your windscreen after that, don't feel bad about giving them nothing, you warned them, after all.
