its a great reply mate, but you dont know who shes gonna show it too in the area
Apologize, and show regret at losing them an she may feel a prat
you send that and she thinks i was right- he was a prat

You just consolidate the loss
but be nice, she may come crawling back when her windows are filthy, but dont make her think that, justr leave nice, let her come bakc nice,
All these custyy complaints are true and funny BUT
you are all on customer service industry and alot of it is down to how you handle it, i had a lady come round back of house the other dfay and really tell me off for leaving front gate open, in my head i said shove it up your arse for £10 you moody old bat, in reality i said im sorry must of forgot, it wont happen again,
Just part of the job, and yuo are the bigger person, and better in pocket for it
