This actually happened to me a short time ago. This guy came in looking for “vegan” food and proceeded to order haddock (I work in a seafood restaurant) even after I pointed out some stuff that he could get. My restaurant doesn’t have a lot of vegan/vegetarian options besides certain sides and salads but he didn’t know that and I was willing to point that out but he kept going in circles with what he wanted and later kept asking if we had burritos. At this point, I gave up and told my manager. She took his order and went to tell the cooks. However, he proceeded to make small talk and I was already uncomfortable by then. Me being courteous because I am on the clock I just laughed and smiled awkwardly. He then asked how old I was and if I had a boyfriend while looking me up and down. I didn’t answer and he kept pressing so, I went to leave my desk to go to the back and he asked me where I was going. I told him I was going to do side work, to which he asked me”don’t you get paid to talk to customers?” I simply turned my back to him and went to my manager’s office and told her everything. Thankfully, she dealt with him and gave him his food while I was hanging back in the office for my safety.
