I can understand the need for loss prevention and preventing "shrink". However, there comes a time and a line drawn when someone enters my personal space.
Now, I'm not an agressive person... I'm pretty passive until I feel threatened. Having someone reach for me forcefully would set me off... Probably not enough to draw down, but most definitely lock them up and to take them to the floor.
However, this is VERY situational. I'd be quite a bit more restrained it were one of the older greeters at Wal-mart. I'd feel like dirtball if I sent some little old lady flying..
