Yeah I suppose so. It's just the guy was very sincere like he wasn't smiling or anything he had this serious expression on and the group of people he was sitting with weren't laughing or giggling either in fact after the guy talked to me they pretty much ignored me. Also the people that work there seem more friendly towards me than before. Still it might just all be in my head. There isn't much I can do and it still could be a prank... oh well
