There were several factors at once. Serving to a customer at 180+ is a bit high. And that particular machine was slightly overcalibrated. It was 193 degrees if I recall, not 180-190. And then, yeah, the cups are crap.

Gonna suggest it’s less simple than that. The mouth only touches a small amount of fluid at once. The temperature plummets really quickly when you sip the hot coffee.
When you stick a finger in the coffee, there’s a lot more coffee keeping the liquid contacting your finger hot. That’s why you sip hot coffee. If you do a quick dip with your finger, it won’t burn.
It’s similar to how you can accidentally brush a hot pan and not get a burn.
