I'd say good, unless you order a cocktail. Something about sipping a beer, wine, or whiskey & Coke out of a paper cup I find cheap and unappealing.
For alcohol, they should serve beer from the can, and wine/cocktails in a glass like in F or washable plastic cup. All other bevs in paper fine with me. This should work with the initiative of eliminating single-use plastics.
Anecdotally, I've had countless experiences when I've ordered a coffee with cream and I get a coffee cup, and a second plastic cup containing 1-2 of those little creamer tubes, napkin and stir-stick. Sometimes, 2 (two!) plastic cups containing the coffee accessories. What an absolute waste of materials and money with a significant environmental impact. Stop that, Delta. Just hand us the stuff and we can manage it from there.
