I used to refuse to even consider variants on smores for some reason I genuinely don't remember, I guess just for being committed to being a joyless pedant. I was like the grilled cheese copypasta guy. I can't believe I was missing out on stuff like this

Never worked there but the Taco Bell subreddits were daily reads for me. I think the most consistently hated were basically any of the gimmick options, like the $1 Crunchwrap Sliders were my favorite food ever when they were around, but I was mortified to learn the employees HATED making them. A lot of the grilled stuff seems to be difficult. Nacho fries, though I don't remember why. I know ordering a bean burrito grilled was considered a douchebag move, but I think they removed the option to do that.
