heres another intersting idea, why doesnt the guy that agreed to come pick up his money quit being a douche bag, do his damn job and come pick up his money instead of expecting his customers to come knocking on his door? At the very least he should be making some phone calls to his shops and explaining why he hasnt shown up in 2 months, Then ask for his money to be sent to his address of choice.....or even a crazier idea, stick to the original agreement of picking up the money every week.
I had a similar experience with a truck guy. He called to let me know what was going on and I just sent him a check for my remaining balance so I didnt have to bother with mailing checks every week.
Chances are, it sounds like the SO guy is planning on writing everything owed as a loss if he hasnt even been trying to collect outstanding debts.
Its not like the OP is "going to lunch" as soon as the truck pulls in the lot. If I neglected to send my customers a bill every month, should I just expect them to hunt me down?
