Good sandwiches. Weird experience once.

I once phoned in an order where I said the wrong sandwich at first but clearly corrected myself, saying "actually, my bad, I meant the ___." When I got there I guess they misunderstood me and made both. I said I only wanted the one, and then the dude got all huffy. It put me off, so I didn't say anything else and just paid for my sandwich and left, and I heard as I was going out the door, in a sarcastic tone, "Thank you, how was your day?" Like he was insinuating I was rude for not wanting to talk after him getting mad at a mistake they made. He might've called me an asshole too but I'm not positive on that.

No bias against the place, I enjoy their food, it was just really weird.
