It also frustrates me how restaurants in international airports only follow the local "meal schedule." If everyone were in the same timezone all day, then okay, I can see why you'd only offer breakfast before 10am. But that isn't the case in an international airport. Why are all the dinner places closed? (Rhetorical question - I know the answer is "$$$")

But if you've been flying for hours, jetlagged from changing timezones, and you still need to catch a connecting flight, you may be ready for dinner/supper. It sucks when you want a more substantial meal, but the only options are eggy breakfast sandwiches and doughnuts.

It just makes more sense to offer options for any time of day in a place that's open 24 hours, where you know the people you intend to serve will be on different meal schedules from what the locals might follow.

And that includes allowing people to buy/drink beer. But alas, those damn blue laws supersede all of that.
