I like marmite and cheese toasties. It's a great combo and no one can change my mind. I also like marmite and scrambled egg sandwiches but this one especially will get a lot of raised eyebrows.
I don't do it so much now but I had a phase where I'd end up gagging on chicken bones often enough that eventually I started stabbing my chicken to see if I could find any bones before I ate it.
When I'm on a work rotation I tend to dump an unholy amount of ketchup or mayo on my dinner. Sometimes I'll go for salad cream if the sauces are really low. People think we get what the passengers eat - we don't. It's super low-grade crap that often isn't what it's claiming to be and it's so bland cardboard has more flavor.
I can't deal with chewy food. If it takes too long for me to chew it will trigger my gag reflex and it's not pretty. I get a lot of people rolling their eyes when I'm being super fussy with cutting off fat on beef, gammon and bacon but that's why I do it. Chewing gum is fine until it looses it's flavor then it will start to trigger my gag reflex if I can't get rid of it right away that I only have it when it's offered to me and I feel rude saying no.
My weirdest one of the lot; I have sensitive taste buds that when I'm ill change just enough the taste of potato (something I usually love) becomes nasty. It's actually one of my early tells I'm coming down with something, if I'm finding potato very metallic and unpleasant tasting I know I have lurgies on the way. It's pretty unfortunate the one thing I often end up craving when I'm ill is a plate of cheesy mash.
