Drill Sergeant Relapse

So, I work in a retail outlet that sells stuff, like retail outlets do. Since I've been back I've been trying to work the retail gig by being nice and smiling and being overall helpful. 99% of the time I'm really helpful, though I've been told that I may be a little to serious and intense sometimes and I need to lighten up and smile more.

So anyway, the entrance is a one way, we ask our customers to go around and use the exit doors to get out of the store because you have to walk through the anti theft device.

Before I continue, I need to make it known that I do not like thieves and liars. They will set me off. So when this guy asks me for the time and I give it to him, he decides its time for himself to leave the store and he tries to go out the door and I politely tell him "sir, you can't go that way."

He becomes insistent and when he fiddles with the door again I make it a little bit more apparent "SIR, that is an entrance only."

So he gets the door open and heads out the door, which generally means he stole something.

I chase him down and go drill sergeant on him, threatening to call the police on his ass and wanting to get in his way just so that I can say he had to touch me out of his way so I can freakin' go apeshit on him (as you aren't allowed to touch shoplifters, unless they assault you first). Of course, I don't have my cell phone and the guy isn't listening and just keeps walking (but truthfully I don't think he'll come back after having to deal with me). So I head back to the store because a 5'3" girl wearing a santa hat isn't all that imposing, no matter how mad I get.

Granted, this is the wrong mentality to have and when I went into the yelling frenzy my coworkers all thought to themselves, "hmm, that must be the drill sergeant side of her", which they haven't seen before. Of course, I was reprimanded because I didn't handle the situation the way they would like me to handle it.

I'm thinking after BNCOC, I'll work there for about three more months and probably put in my two weeks. I like working there and all, but I really do need to get on with life, and the retail gig is not my choice of a place to work.
