My boss was away for the weekend and so the evening before he came back, my co worker cleaned the cafe extra hard so that he hopefully wouldn’t complain of it being dirty. Anyway he comes back and decides the cafe isn’t clean enough and so he throws away both of our travel mugs cause he was annoyed. We use the mugs cause it keeps our coffee warm for longer as when it gets busy we don’t really have time to drink our coffees. I wasn’t even working that day and he still decided to throw away my mug. Also these are mugs we bought with our own money and we have never been told we can’t use them.
