I was working in the seafood department of a big chain grocery store. We had a massive promotion for king crab legs. The store I worked at was the closest to the corporate hq. On the first day of the promotion the regional manager came to visit in civilian clothes. He asked me how the crabs were selling and I was like, "Pretty slow so far." He then introduces himself without mentioning his title. I shake his hand tell him my name and ask him where he works. He huffed and puffed his way out of the store and a week later I was transferred to a store 30 miles away from my place. I didn't really tell him off, but I think my not acknowledging who he was probably pissed him off more than if I called him a bellend.
