I feel like this might be an American problem

Fast Food Nation, the paper/plastic cups are flimsy and need a lid for structure.

We get so used to it that when we eat out, we want straws.

I've never really cared. IF they bring wrapped straws, i'll generally not open it and stash it in my car for the next time a fast food straw breaks. If it's open, I use it because it seems more of a waste to throw it away unused.

There probably is some decent point to the server groping all over the outside of your glass or the dishwasher handling it, but i'm not really a germophobe.

I'm unsure how much benefit reusable straws really are because at a restaurant, they're probably gonna give you straws anyways and I don't think they'd put unused ones back in the box, especially post covid.

If you want like a mixed drink or a pop out of a glass while lying on the couch or in bed a straw is useful too, thats the only time i ever use them. My fiance likes a ton of ice in everything she drinks so she uses our metal straws for everything. I still prefer drinking out a can or a bottle with a screw on cap for most things when im lying down.
