Right from the start: I want no pity.

Frequently I am one of the crowd. The moment I don't control myself I fall into wallflower mode. But rarely I have good experiences with women and am more confident, which I radiate.

There is this supermarket I've been going to for 6 years regularily. They know me, I know them.

But each time I am in a good mood, happy - which is as I mentioned rare - or with a good looking woman, flirting, and I am there to sign my receipt to verify that my signature on my ec-card is valid, the male cashier(it's always a male cashier when the following happens) tells me that my signature was wrong.

Whenever I feel bad, that never happens.

To clarify, my signature looks the same.

So I hope everyone realizes by now that this is a means by the cashier to make me be the good old submissive shit again that makes him feel better and in control again.

I know this. I know what is going on. I say: "No, it's the right signature" but my body goes immediately into old habits.

Does anyone have an idea how to use this opportunity to grow?

Calmly tell him that it is the right signature, and that if it isn't that you would like to see if the manager has the same opinion.

This is great, especially the "Well, why don't you call your manager to see if he has the same opinion about this?" WILL put him in his place. Especially with more and more people queueing up and listening. I will use that. Thanks.
