"I wanted to thank you and your son again for the relentless battle you waged against the invading force of baby wipes [flushed down the toilet, clogging the plumbing]. When I called you, I had no idea of the nightmare that was about to consume my weekend. Both you and your son are to be commended for your professionalism and dedication while blowing your entire weekend at my home." If anything good came out of this, it's knowing there are honest, dedicated people out there who do a great job and take pride in it. Your persistence, I'm sure, saved me an even bigger mess."
