From the way you've described it, it's clear your boss didn't mean any harm; he just assumes everyone else does because he enjoys super spicy food... Wrong assumption đ
This contrasts sharply with the experience of an old friend who tried to play a prank on me when I first tasted sushi. He told me the wasabi was delicious and served me an excessive amount. What a tasteless joke! It took me a while to recover while he laughed himself silly. I didn't want to eat sushi again for quite some time, until a good friend invited me to enjoy it without any such tasteless jokes.
