Non paying customers
I've had a couple of customers like what you're desribing. One of them was always late, insisted that the check had been mailed on time, etc. I refused to do any more work until I received a check in the mail by a specific date. Needless to say, I didn't receive a check, and they didn't have any lawn service for the rest of the season. The other one wanted work above and beyond the contract. When a bill was presented, I was basically called a liar. Never received the money for that one, either. My point is, drop clients like that like a bad habit. If they don't want to pay, get them off of your route. It's not worth the headache trying to get your money out of them.
