Force your way back into your spot (dominant)

You head on over to the man that "took" your spot. You don't talk to him, but you nudge your way in, still holding your beer.

The people are so close to each other at the bar, you're physically touching both the lady on one side, and the man on the other.

You don't care. You consider this the spot you had, and you've got it back. You turn around and observe the bar.
