I especially dislike the age requirement of 21 instead of 18 that result in being asked my ID when I'm in my 30's because it's very hard to differentiate between adults (in contrast someone under 18 is easy to spot, so there is way less ambiguity and ID asking, you really have to look like a kid to be asked).
