Aggressive panhandlers

The other day I was eating lunch at a local restaurant. There are two parts to the joint, one half where you eat, the other half around a corner has the seating and soda fountain, etc. Both sides have an unlocked entrance, however I feel that I should mention the dining side is not viewable by the employee running the counter.As I was sitting there eating alone about 3 table rows deep from the entrance, facing the entrance and window that looks out to the street, I noticed a homeless man started to talk to a female pedestrian. She kept walking and clearly did not want to engage with this man. He kept following her for approximately 50 feet or so, after she turned around and appeared agitated by him following her and I assume told him something along the lines of "fuck off".As he mades his way back to the spot he was originally standing, he notices me through the window. I notice him notice me, and think to myself "I know this dude is not about to walk in here and ask me for some shit while I'm trying to enjoy my shwarma". I was wrong.He walks in the door and proceeds to walk up to my table, (opposite side of where I'm sitting) as he gets about 4 steps from the opposite side of my table I stand up and back up. He placed both hands on the table in a standing over kind of way. Before he said anything I tell him to get away from me. Perhaps this wasn't the most diplomatic way of essentially saying fuck off, but I wanted to make it clear he wasn't going to take control of the situation and I was not going to back down. He replied with "get away from me?!"... appearing irritated. I reply with "you need to leave". He thinks for a moment, and walks away and exits the restaurant.I wasn't terribly close to drawing, however this is the first time I've had my thumb hooking my shirt. (IWB at 4 o'clock).Would you have handled this situation the same, or differently? Looking forward to input! via /r/CCW http://ift.tt/2mWwUUo
