Their coffee in the U.S. is the worst too IMO, aside from the occasional awful gas station coffee and I wouldn’t be shocked if they were buying Starbucks roast since they also sell it in bags in supermarkets. But, of course, it’s like McDonald’s- no matter where you go, you know what it will taste like. So people rely on it.
I avoid it as much as I possibly can (it doesn’t help that I used to work on a show in L.A. that was partially sponsored by Starbucks and it was that or our other sponsor, Red Bull, if I wanted caffeine while working). The only times I go when I’m not traveling and have to make a caffeine pit stop and there are no other options is when all the other local coffee places are already closed since they all close earlier than Starbucks and I want to sit somewhere not at home to do something.
Other than that, I always go local. And here, a lot of the local places have drive-throughs, so even that convenience Starbucks offers is unnecessary. They’re usually cheaper than Starbucks too. And, of course, better coffee.
