I think the guard felt different from the others where he was, standing in a place, seeing people come in, and not even saying good things, and you were one of them, but then you asked him a question, maybe he was having a bad day, and he expressed all his annoyance with you, you were like the punching bag for him to drain all his anger, I'm not questioning you, I'm just putting myself in his shoes, and thinking about the reason why he would act like that? But that's over, next time tell him at least it's good. Blessings 🤗
