Do any fast food restaurants still serve Coke and Pepsi at the same store?

Never seen it. I believe that the soft drink maker gets a deal with the whole chain (at the corporate level) and that all the stores have to follow whatever corporate says.

The only place i have seen both Pepsi and Coke products is in some of those huge gas stations that have drinks and food – they’ll have those HUGE soda fountains and you can get both Pepsi and Coke. Like the QT chain in the southern US or the Sheets chain in the mid-Atlantic.

I’ve only ever seen one or the other.

I only remember seeing only one or the other. I once asked for a coke and was asked if a Pepsi would do. To me coke is a generic term.

@LostInParadise Always ask for an RC Cola. Make them apologize for not having it and only having one of the other two.
BTW I prefer RC over either of the other two, they are sweeter tasting to me.

Usually, the store or chain has a contract with a bottler to supply one or the other, along with other products in that bottler’s line. It would take up more room in the store if all products of all/both bottlers were to be on hand for sale.

I’ve seen the mixed fountain soda somewhere, but I’m not sure if it was fast food, I doubt it was. I know I’ve seen it, because it’s shocking.

Story time: my mother was/is a Cocaholic. Loyal to a fault to Coke. We always went to McDonald’s for fast food as a kid, because Burger King had a Pepsi contract back then. I remember the first time I went to BK I was in my late teens, and I had no idea what to order, and the burger had a bunch of stuff I didn’t want on it.

I remember when you couldn’t even get both at the convenience store. I think that changed in the 90’s, but I still come across it from time to time, and I make a note to avoid them because I hate Pepsi.
I have yet to find them both at a restaurant, though.
