It looks suspicious as hell, even if what you were doing was actually innocent.
No, it doesn't. Every book is tracked. The second they accept a book, whether a new book from the loading dock or a used book from the buyback desk, it's in the system with its own sticker, and at least 3 employees saw the unpacking or purchasing happen. If I was stealing books, if there was any reason it could be "suspicious as hell", then where's the audit? If they can give me a list of which books I've sold them and claim this must be some criminal scheme, then why can't they simply count their copies of those titles and prove that I stole them? I'll give you a hint: because they did, and they know I didn't.
Not all coincidences are automatically "suspicious", and they had reams upon reams of camera footage and inventory data to catch me if I'd ever done anything legitimately wrong. I have no doubt they'd have charged me if they actually believed I stole anything or broke any law. They were the biggest assholes anyone there had ever worked for. They didn't charge me, because I never did anything wrong. I never stole anything or accessed any information that any other student couldn't have. It's as simple as that.
These are the same people who pay students $7.25/hour and external employees $10/hour, because "students get all their tax money back anyway, so you're practically ahead of the $10 people, anyway." Yeah, and I'm the fucking tooth fairy. I'm sure all of your half-time, temporary $10/hr employees were in a >27% tax bracket. They also had big, proud banners all over saying "our earnings go to scholorships". These banners failed to note that you can pay your management any number you damn well please and then call the rest of it "earnings", and also failed to mention that they were tens of millions in debt from mismanaging their remodel and so hadn't really *had* any earnings left for scholarships in years.
They also effectively threw out any book the school wasn't using anymore. They had people who would come in, scan all the books and compare them to the wholesalers and Amazon prices, and simply tell us how much money they were going to give us so they could cart it home and put it up online. We never turned down a single offer, ever, despite most offers being maybe 5% of the books' current value. I went to see the store manager and said "Why do you do this!? I'll buy the books from you if you just throw them away like that! I'll get a business license and go through the same moron channels these chislers went through to buy books from you, and I'll pay you *10 times* as much". She didn't have a good answer. She said there were always people after her to buy the books, and it was just a headache, and even if I was licensed she might not want to do business with me. "Do business with me?" She made it sound like contract negotiations; and yet she didn't provide a single specific reason why it would be complicated. It was just inconvenient, and less annoyance to pass the costs of those wasted books onto the students than to recover any real value. I was offering to pay her 10 times as much to literally dumpster dive as someone else was offering her. I'm not sure there's anything complicated about doing business there, or anything short of fucking idiocy to turn down that money. They were just lazy, corrupt fucks, and that's all there was to it. Every long term employee I ever spoke with immediately agreed when I brought up these bizarre situations that there was nothing else to it; corruption, greed, and incredible laziness.
They lied to everyone they could, manipulated anyone they could, and fired/censured anyone who got too close to the heart of their game. They were corrupt and lazy beyond belief, and that's all that was "suspicious as hell" about that store or anything I did there.
