Based on your comments here, and your post history, it sounds like you may live somewhere with an awful culture. It also sounds like you're really negative and disdainful of others, and also pretty passive, being willing to move twice for strangers who wanted your table. All this sets you up for a bad time.
The way to not be bullied is to not let yourself be bullied. Don't give someone else the power to decide how you feel. Laugh at them or ignore them and move on instead of dwelling in anger or resentment.
I live in the US, and while bullying does happen, it's far outside the norm. I've never experienced it in my professional life, and instances even when I worked retail and grocery when I was younger were always addressed. Bullying is something children do, and adults with personality problems.
I don't know if I was insinuating that your experience here is your fault as much as I was giving explicit reasons why it's probably your fault.
Labelled by who? The stranger who wants your table? And then what? And why do you care? This is all you, trying to people please and avoid conflict. Assertiveness is a skill you can learn and would go a long way toward helping you with the problem you're describing.
