It's absolutely possible. It would depend on the store but I'm guessing a store that has a loyalty program is interested enough in analyzing customer data that they would use your credit card as a unique identifier of you as a customer, especially for transactions where there wasn't a loyalty number entered.
Similar to that, just because someone works in IT, doesn't mean they can fix your computer problem. I've worked with a lot of developers who were great coders but couldn't resolve networking or random OS issues.
Not exactly secret, but not very well-known. In many states your credit score can be used as a factor in determining the cost of auto insurance for you. Lower credit scores can equal higher premiums.
I've found it helpful at work for things like preparing agendas for meetings, or creating an outline of a presentation or document I need to write.
I've also found it helpful when I'm trying to Google something where I need to be pretty specific and then I can't find exactly what I mean by searching.
Here's something totally bizarre that you might it might not care about.
The other day I brought up Metroid on the Nintendo Switch NES app (the one that lets you play some NES games with an online subscription.) After playing for a bit, I wanted to show him the Justin Bailey code. But I couldn't remember it exactly at first. So I tried it in various cases, and when I enter the code with all lowercase letters, it crashed the game.
No idea if it'll do that for everyone, or if it did that on the actual NES, but I tried it a few times and it crashed everything.
I received the offer on my 16 year old Reddit account, but not on another account I have that's more like 12. Not sure if they went by account age or activity or what.
My son is a voracious reader, and he has the same thing. He's 15 now but still, every so often, he'll say a word and it'll take me a minute to figure out what he means.
I had literally no context going into this movie other than it was about a chef and/or a restaurant, and it was well-reviewed.
By the time I figured out that it was basically a horror movie, which I'm not into, I had already seen a couple of graphic scenes that I wished I hadn't, so I turned it off. Disappointing because I like the actors in it, and the story was compelling at first.
