Need to define what a messer is though,
Customers who have been with me a while and ask to skip jan, I dont mind. Provided its only one or two, because lets face it, it isnt going to make you broke is it!
However, if as sometimes it happens, where good customers do turn into messers and you see it happening. These ones get one chance and one chance only.
Yet, when youve been doing this work for a while, you can see signs of a messer before you get to their house and then when you meet them, you have a gut feeling. If you still take them on, then fine whilst it last but as soon as it turns, they get dropped.
