Many (real) fast food places (burger places, etc.) won't serve you a straw in the drink. They'll either place a sealed one on the tray or you'll have to get your own from a dispenser. I think Bitt is talking mostly about sit-down restaurants with table service. I do still call some of the places fast food though.

Some places up here will put a straw into the glass/cup when you ask for water. Now that's just plain wrong. Have they ever tasted water through a straw? It completely alters the taste.

I've always seen straws served with any type of fountain drink, carbonated or not, so that includes ice tea. That goes for pretty much for most places I've ever been to. I've never ordered a fountain drink for myself in my life, but I've also received straws when ordering juice, which again is strange.

Thankfully I've never seen nor had one served to me when ordering beer or wine. Because frankly, that would be the last straw.
