would this be a red flag? - customer is already late on her payment. she wants me to continue service, saying she will pay on the 20th. big problem though, the payment sh'es late on, was due 4/01. if she pays that one april 20th, i can be certain, the next payment (due 5/01) will be late also. i was mentioning this to my wife the other day. my wife called me from the office yesterday, " just want to let u know, that customer who didn't pay her bill...her house just went on the market today." would u continue service? would you discuss it with the customer?
