Got humiliated in front of EVERYONE at the gas station because they thought I shoplifted

EVEN THOUGH I HAD ALREADY PAID AT THEIR SELF-CHECKOUT REGISTER

AND IT WAS OVER A BAG OF CHIPS AND A SMALL JAR OF NUTELLA

Now, to make this situation make sense, there’s this display sign that’s usually in front of the self-checkout register. I didn’t think anything of this because it’s usually there, so I went up and paid for my things.

Well apparently that register was closed(there was no sign), but it still let me pay for my stuff. And an associate didn’t say anything to me until I had already paid for my things and hit the no receipt button. I told her I had paid for my things but then she was like “I can help you over here.”

Well then the manager(I’m guessing) and has to check the purchase history in front of everyone who’s waiting, and there I stand, looking like a thief all because I didn’t want to pay twice.

And then when the manager finally let me go with my things, there were a bunch of people staring at me.

Why would someone steal by paying for their stuff? I swear bro 💀 Is it cause I look young?
