I live in a small college town. As such, there is only one Subway franchise here, and I happen to frequent it quite a bit; I love Subway, plus one of my good friends from high school works there, so whenever I'm there and she's working, we have a little chat if we can (if she's serving me, that is; obviously if she's busy working we don't.)
Anyway. Yesterday after classes, I hadn't eaten all day, and I was in the mood for a roast chicken sub. I was starved, so I ordered a footlong, and I was also having a serious protein craving, so I ordered double meat. Anyway, after the toppings/sauces had been put on, I moved along to the cash. My friend (who had made my sub for me) told the girl at the cash what kind of sub mine was, and it was duly rung up.
At which point, the girl at the register went, "WOW that's an expensive sub! What in the world did you put on it?"
I don't know why, but I immediately went on the defensive. Maybe it's because I'm overweight and am always on patrol for rude, ignorant remarks, but when she said that I just felt like, for some reason, I had to explain my food choices to her. And as far as I'm concerned, it's none of her business that the sub was expensive. Yes, it was, but as long as I paid for it, it's none of her damn business what it cost, or what was on it.
Like I said, technically not bad service, but it just....it bothered me. I felt the same as I would if I went to the drugstore to pick up tampons and the cashier commented on my purchase. It's just none of their business. Say hello to me, ask me how I am/how my day is going if you like, and then check me the hell out. Don't comment on what I'm buying, because it doesn't concern you. Gah.
Edit: OK, obviously a lot of people disagree with me on this. That's fine; obviously I was aware when I made the post that it wasn't technically bad service (I even said so in the post); I just think, seriously, that it's not a cashier's business to comment on anything a customer buys unless their input is asked for.
In any case, thanks for the feedback!
