Few weeks ago, my friend and I decided to meet at Starbucks but I was a bit early so decided to order and wait for him. I’m not a coffee person but no big deal for me if we’re meeting in a coffee shop cause you know, Starbucks (like other shops) have non-coffee drinks. But i felt awkward when I asked the cashier for a hot choco - some people in that shop looked at me. No over reactions, but i feel like they were surprised with what i ordered.
I suspect that they looked at you because your were obviously nervous.
No one cares, coming from a non coffee person as well. My wife is a teacher and gets a lot of Starbucks gift cards, neither of us drink coffee. So we just use it for road trips and hot chocolate.
