being able to specify allergies as much as you want
And you trust that?? If I had a serious food allergy I would absolutely NOT trust that a food delivery service would communicate those effectively given how much they push restaurants around, up to and including adding restaurants without their knowledge or consent.
I suppose in the strictest sense, sure, these apps are convenient, but you sure are paying a lot for it, and some restaurants charge extra for it on top of the fees, and the delivery folks aren’t getting a fair cut of the fees. Most of the fees go to big tech.
I’d rather they were destroyed, but practically speaking that’s impossible, and this sounds like the next best idea to me.
