Never sneezed while eating Chipotle (sounds awful), but I have a couple things to throw in to the discussion.
My stepdad is the loudest sneezer I have ever seen/heard. He shouts a long "AHHHHHHH" before sneezing (rather embarrassing in public). Also a weird vomiter (sounded like he was shaking his head with his mouth open, kind of a motorboat while vomiting...)
Weirdest nose-related incident while dining: I was in maybe 4th grade, eating at a special table on ground hog's day (i think it was just student council kids, and a news crew was there for w/e reason). We had some of that green jello with the bits of melon and the white grapes in it (love it). One of the other kids said something funny, and I laughed hysterically while swallowing a bite. I had chunks of green jello with the chewed up melon bits and probably plenty of snot coming out of my nose onto my tray in front of these news people and the principal (I dont think they were filming or even paying attention at that point). The inside of my nose had that "raw" feeling and it was really annoying.
