i have a code of practice to help stop certain things cause a prob - make new customer pay so many months up front and give them written rules of how we work - seems to do the job.
How the heck do you get away with charging them in advance?
The written rules of how you work is a great idea tho, explain that rain makes no diff and we work in it sometimes etc.
My favourite so far has to be the already sealed envelope!!!
Ive had a few envelopes and cards returned with no chqs in tho i might add!!
And i bet they think we must be dumb because we'r window cleaning!!
