I work next door to this walgreens so I'm here all the time. As I was checking out Marrietta who normally is very pleasant was questioning my $50 dollar bill. It was an old bill without new markings. She kept looking for marks like a strip or halograms but I told her that I didn't think they have those marking on old bills. She kept saying that she thinks its fake and even the person in line behind me told her the old bills didn't have it. Marrietta called the manager Anthony Swanson and he kept looking for a strip or halogram as well. He then told me he couldn't except it because it looks fake. I asked him how he can tell and he made up the fact that it felt and looked fake. But he couldn't test or prove to me that it wasn't real. I had it checked later and it was definitely real. I'm not upset at all in them thinking it may be counterfeit that's their job but they couldn't prove it and ended up embarrassing me. I will be making a formal complaint to corporate as well.
