Trespassers are ridiculous

Honestly normally trespassers leave without issue when I ask them to but tonight I had some trespasser tell me that I was overdoing my job because I asked him which resident he was coming to see which is literally part of my job because they're supposed to come check in up in the front. The guy was chilling by the side door which at almost 1AM I'm sorry but that's sketchy. He then keeps telling me how to do my job which is a no no for me so I shut him down right then and there and say my orders come from my supervisor not a stranger who's trespassing and avoiding answering my questions that I am required to ask a trespasser.

It just frustrates me that people who trespass just go into automatic disrespect sometimes like I'm not rude about it I don't go cussing at anybody. I just do not understand, I would be acting the same way no matter who is at that side door, a trespasser is a trespasser plain and simple.
