As someone from the west coast of The States, I can’t say I’ve ever seen a hot drink vending machine in real life. At least not here where I live.

We used to have them, but I haven't seen them for over a decade now.

If you remember the Terminator 2 movie, the scene where a security guard gets a cup of coffee, those are the kind of dispensers that used to exist.

(The link above shows the scene I'm speaking of. I tried to embed the URL into this comment so the picture itself would display, but I couldn't figure it out.)

Also from the US west, I've seen a bunch of hot vending machines! In several hospitals and schools in different states, a few gas stations. They will have coffee, tea or cocoa selections, a cup pops out and gets filled with fresh brewed coffee. They were usually around 1.50 to 2 dollars a cup, maybe more expensive now though.
