If you happen to be an employee at a thrift store, or a second hand store, do you ever take a look at the stock yourself and maybe take some things for yourself? Or pull items aside to buy later? I knew a few people who worked at a thrift shop and would often find new clothes. He would buy some of the clothes himself, so that he'd get first dibs on them. When he was done, he'd donate the clothes back to the store, no joke.
