i am not rich by any means, but i do have a safety net put by to keep me a float in these times of troubles, (credit crunch) ect, if you have custys for a few years you get to know them paying wise, usually its the lady of the house, who will answer, could you leave it until Monday, now i sense they are having difficulty, call it intuition, and i will say would you like me to call on the next clean, and the smile on there face says it all, i work with my custys, and the answer is work with them not to put pressure for payment, 10 out of ten pay me when they have it, pity we could not charge extra, but this is my way of securing my custys, how do you secure your customers
