Yes, I know what “hot” means

I like spicy foods. I put hot sauce on practically everything — without it, food is bland and boring. Why is it that this surprises people?

Example: I frequent a particular take-out stand for lunch a couple of times a week. I often order some chow mein and some hot-and-sour soup. Every time, the owner hesitates, peers at me, and says, “Very spicy!…OK?”

Example: I was at Subway. I asked for hot sauce on my sub. The “sandwich artist” asked me if I was sure… “It’s very hot.” Yes, I was sure. I like spicy. “Really? You don’t look like you would.” What’s that supposed to mean?

Alright, are these things not called “hot-and-sour soup” and “hot sauce”? Am I so pale and sickly that shop-owners fear for my safety?
