i am a shyte bag I don't like confrontation. ill have to grow a pair
I hate confrontation too, but still tell them the truth in a polite and diplomatic way.
If I am owed for 2 or 3 cleans, I leave a note in their door stating how much they owe, then leave it at that.
If they tell me 'not today' more than twice without giving a good reason, I just say 'no problem', walk away and stop calling to them.
In both cases, most will eventually ask why I stopped calling.
It is very easy to tell them truthfully that I couldn't find them in to pay me, so didn't want to add to their financial burden, or in the second case that I didn't want to keep bothering them if they really didn't want me to call to them.
It leaves the ball in their court every time, and I have been honest with them without causing a scene.
John.
