I watched him as he waited to intervene a few steps from us, platter in hand. Eventually he gave up.
In any case my experience, after 30 years of eating spicy food, is that I apparently don't feel the usual effects people who like spicy food do.
What happens instead is that the spice forces me to eat slower and thus get more flavour out of the dish. After all, "spicy" is technically not a flavour, so it mixes well with just about anything.
I did have a period of gradually increasing the dose, though, at the end of which I discovered that capsaicin is also excreted through urine. It is not a pleasant experience.
