Here are my Terminal Peeves

1. The signs to the airline lounges are hard to see.
2. The only restroom that is open is far away.
3. There is only Starbucks for coffee in the terminal.
4. A person taking up the time of a gate agent when you have an important question.
5. The layout of the terminal is so confusing that you go around in circles trying to find where your gate is.
6. The departures level is so slow that you wish your taxi or party dropping you off would just put you in the arrivals level and you can walk up.
7. Curbside checkin is closed when its supposed to be open.

What makes YOUR question more important than theirs? Do I sense some DYKWIA here? :)
Curbside check-in is a think of the past, IMO. I've only used it once and wasn't exactly thrilled with it. With OLCI being prevalent nowadays, the "regular" check-in is much like the curbside check-in (essentially just a bag drop-off).

1 - People with roll-a-boards (I'm sure there's at least one, but I've never come across anyone who could competently drive theirs around the terminal, especially when the restroom comes into play.)
2 - People who need to have their bag next to them on escalators, because no one else could possibly be in a hurry (which, of course, is made up exclusively of people from #1.)

+1
Not just an airport problem. But the presence of rollaboards makes the risk of an accident far worse (e.g., domino chain of people falling down the entire escalator).

Terminal peeve from last week: on a YUL-LGA-STL-SEA itinerary, clearing TSA security twice (on top of initial screening at YUL); once because LGA Concourse B and C are not connected for AA :rolleyes:, and once because AS's gates and AA's are not connected behind TSA at STL :rolleyes:.

Two more airports to cross off my "I'm willing to connect here" list.
