At least in NYC most immigrant establishments will serve you "white people hot" if you don't ask for "regular hot". Saying this as a white Polish, it took me a while after moving there to realize that I was being served a "white people hot" hot, and also that apparently Poles love their food way hotter than other (most?) European nations. That's even more interesting if you consider our otherwise fairly bland national cuisine. It's rather unusual for a Pole to avoid spicy food at all – if someone does, it is a notable exception.

Once I learned it, I would place my orders saying: "– Yes, hot please. Your hot, not mine."

As for spicy snacks, nothing can beat Takis Fuego! :)
