I have a freind that used to be a shop owner, he is now retired. He now fills his days by shopping and returning things. Buys on Monday returns on Friday. He is thrilled with himself when he can make a retailer feel bad with his condicending comments on the product he is returning or evan the actions/words of the retailer. I believe he took so much grief from customers at his shop that he is on a lifelong mission to get his pay back from his many years of abuse. Do we as shop owners all end up like this?
