I'm not going to give up my table
Why would you be so obstinate?
The cashier annoyed me, I want to make her life harder
I'm sorry the cashier treated you like that.  But it's rude to punish people at a restaurant by not being accommodating.  They weren't the ones responsible for being rude to you.
The cashier is part of the problem, she shouldn't be acting like this.
I get it but you shouldn't take your anger on other people in restaurant. If you have problem with the cashier talk to them about your concerns.
