This is not hard to do at all. I find employee shirts, vests, etc. all the time at thrifts stores. Walmart, ACE, AT&T... sometimes they still have the name badge on them. I'm always telling The Wife about all kinds of nefarious stuff I could do with those items...
However, I'm not a negro, so I don't steal stuff from department stores.
Their first warning sign should have been when a nigger walked in wearing a WORK uniform.
