Looks like troll bait, but I'll bite: is this where your armchair psychology and wannabe intellectualism comes into play and you tell me I'm overthinking it? Or was that someone else?

It was weird because I've never paid for something at a checkout without a word exchanged, and it was pretty obvious he was ignoring me, so if someone's intentionally ignoring me, I'm pretty sure that counts as having to do with me. You can tell when someone's intentionally ignoring you, right?

And to answer your question, he was talking to other customers just fine, so it was pretty obvious that it was just me, but you're welcome to try and gaslight me if ya want :-)
