ever had a customer tack on a volutary late fee? Customer called me last week to tell me they would be a couple days late with payment. IT is a community center and thre board members have to sign off on the check. DOn't ask me why. that's the deal. they were having trouble all getting together this month. I was fine with it. today one of the board members shows up, with cash and has added a 5% late fee on top of that. She told how great the yard looks and how much more reliable I have been than the last guy they had. thought that was pretty cool that she A) was honest with me that they would be few days late an B) added the late fee on her own.
