One of the interfaces I use at work requires regular reauthentication (sidenote: I’d like to thank autocorrect for “correcting” that to “resurgence ovulation”). At sign in, it pops up a usage agreement, which is tedious but NBD.

What annoys me is that (in the UI it offers, obviously one could circumvent this) you have two and only two options: “OK” or “Got it.” No "I don’t accept or “log me out.” I’d even prefer just “OK” over that - it feels like it’s trying, poorly, to railroad me.
