On regional jets, the hail (or small chips of ice) that come out of air vents are annoying.

When the FA comes around with the snack basket or to take drink orders, the people who act as though they’re at Per Se, and ask the FA to explain the entire drink menu and the pros and cons of all of the snacks, are so annoying!

It’s just a bag of junk food and a medium-quality drink. Just say “red wine”, “Scotch” or whatever; don’t expect there to be a vintage 1985 port on the menu and if the port is vintage 1986 instead, don’t get upset!
