This is actually a legit concern for some people with handicaps. That said, the number of people that just get handed a straw as a matter of course far outnumbers the number that needs it because of handicaps. And of course carrying your own around is a thing.
It’s a fair point that some people would need a straw to drink, but I don’t think it’s entirely unfair to expect them to have a reusable straw or something in preparation. Certainly it seems more reasonable than having the remaining 99% of the population default to having a straw, especially when they probably don’t use one at home anyway.
I 100% agree. At the very least, I don’t think it should be the default expectation that people use and discard a straw with every meal, regardless of what it’s made of. Personally, I have three metal straws. One is a plain straight one, one has a bend in the end, and the last one is collapsible.
