If I ask if a food is spicy at all, and you reply “No, not at all! You can barely feel it!” then that is a contradiction. It is spicy. It may not be very spicy, or even moderately spicy, but it’s still spicy. Please just tell me that straight-out.
I know there’s a good chance you’re mocking me in your head when I say that I cannot handle spices at all, and that even the mildest of sauces, that you insist are barely there, are going to hurt, because I’m mocking me too. I know I’ve got a child’s palate when it comes to spicy food. I know it’s almost laughable, how badly I react to even table pepper in more than the most minuscule of doses.
But if I ask “is this spicy,” and you answer “not at all,” and then proceed to tell me that it’s mild, then I will still consider it too spicy.
If I ask “is this spicy at all” and you say “no” while knowing that it is, just a tiny bit, because you can’t imagine anyone reacting, then please don’t be offended when I take one bite and then throw it out, because I asked for a reason.
It’s a dumb thing to talk about, but… yeah. Just do your cannot-handle-spices friends a favor and be honest when they ask. Mild is still a level of spice.
(This goes doubly for strangers, because if they have a digestive problem like, IDK, ulcers or something, then spicy food can irritate the stomach lining further and cause extreme pain. Some people claim that capsaicin can be used to treat ulcers, but you know… just play it safe, yeah?)
