Basically, free refills in diners for coffee, and tea is rarely hot enough when I'm out for my taste. Nothing worse than being served lukewarm tea. Also the water is cloudly because they don't flush out that little spigot as often as they should.
At home, it's mostly tea, although recently I've pulled the coffee pot (which we've had for "company" for 20 years) and have left it on the counter.
And McDonald's makes good coffee and a large cup is a buck. Nice.
Restaurant tea service in the US is dreadful! So often just a cup of warm water with a tea bag on the side.
