Get the hell out of my personal space!

[Jack7957]

I can only remember one incident I had while checking out at a store. The person behind me, I don't know if they knew they were doing this or not, kept pushing their cart just lightly into me. After the 2nd time, I figured if they did it again, I'd have to do something. So the next time they did it, I reached back, without turning around, and pushed it back into them. I heard an "oh sorry" but did not turn around or answer back.

Me: Excuse me, you're standing too close. Can you step back?
SM: I'm not.

What does he mean by i'm not?

I expect to his tiny mind standing so close that he's breathing down a person's neck isn't too close. Sadly, there are a lot of people who share that view.

Heheh, that's where I do the following:
1) Put hand on hip so that extremely sharp elbow is jutting out
2) Pop hip out and tilt head so that I look like I'm trying to remember something and either
3 a) Turn around and hit space encroacher with sharp elbow or
3 b) Pretend to lose my balance on my high heels, fall a step back and jab space encroacher with my sharp elbow
