Gluten and lactose-free options are usually more expensive than regular food. So it isn't even farfetched.
while the reason for that is usually that things that contain gluten or lactose need to be replaced with other things that dont, whereas if youre sprinkling peanuts on say, an ice cream cone, you could just.... not do that....
on the other hand prices for alternative food choices ARE absurd.... a bag of gluten free flour might cost 10% more for the manufacturer, but theyll charge you 500% more for the final dish because they know damn well you have no choice if you have a legitimate allergy
so yeah, i can absolutely envision a shop charging you if you wanna OMIT the penuts on top of your dish
alt foods are a whole nother can of worms, and idk if its entirely consumerist, especially if you eat them out of necessity as opposed to some kinda trend, but the whole industry is a joke
hell, the peanut analogy isnt even far off, since some companies WILL add certain allergens to food for unnecessary reasons and then charge you more for a varient without that ingredient
a cereal manufacturer might add flour to otherwise gluten free cornflakes, just to give in a nicer appearance or make it slightly crunchier or something, alright fair enough... but then bring out an identical product without that final sprinkling of flour and charge you more for it, not for a version with a replacement for the ingredient, just a lack of it
