Worked at a cell phone sales job a few years back. We'd recently gotten a new up and coming manager at our store and he had a head full of steam. One day, he got on our cases about not attaching enough data services to phone sales and told us we were NOT allowed to sell a phone without attaching data of some kind (back then this included text plans, navigation, etc.)
Well, I told him straight up that I was not going to miss out on a sale because of a metric that was hurting his bonus, not to mention the fact that what he was asking was unethical. He didn't like that so he sent me home for the day. Well, the next day I worked was a Sunday, which at our store you worked alone. Worked the Sunday, very uneventful.
Monday, my day off, rolls around, and I get a call from the Sr HR lady asking me to explain myself for what happened on Sunday. I had no clue what she meant. She went on to explain that Joe, the manager, was accusing me of putting my pubic hairs in his coffee cup. This was news to me, which I told HR lady, to which she responded, "Okaaay... we're going to have to review the cameras before making a decision..."
Well, they reviewed the footage and they found "nothing conclusive either way." Obviously I had no interest in working with this A-hole any longer, begged the DM to let me transfer, even if it meant loss of hours or pay, to which she responded, "There are no openings at other stores, you and Joe will just have to work things out."
Needless to say, I didn't go back to work there... The best part was, about 2 months later I heard from my ex-coworker Rob that Joe had been fired. The reason? He told Rob he would fire him if Rob didn't wash/clean out his own car since "We can't have customers seeing you drive up in a car like that."
Worst part is, I didn't actually put my pubes in his coffee cup, but damn do I wish that I had.
TL;DR: Boss falsely accused me of putting pubes in his coffee cup, wish I had.
