Here's the situation, last month at the end of the month i gave a customer a bill for approx 172$<p>She handed me a wad of cash. (little old lady that has never cheated me or questioned my bill before.) When i counted it at the truck before i left i only counted the 72$. I am SURE that is all i had. I figured they had jsut gotten back from vacation and were short. Being a long term customer i paid it no heed thinking she would pay it this month. <p>I sent her the bill and got a call the next day. She says that she paid the full amount. She has asked me to "double check" my books. I am sure that i only counted the 72$. I would hate to lose a long term customer over this because she has been really very wonderful. (And her husband was my fav. english teacher in high school)<p>What should i do? Write it off? Send out Vinny and Guito? Other options?<br>Thanks for the help guys. Have a good day!
