People wearing their badges while a half mile or more away from the CC - or after 8 PM.
Going to have lunch/to the convention floor and seeing a flood of STUDENT/PARTICIPANT badges, but not a single PARENT/CHAPERONE badge with the hundred kids that have descended upon the area with no supervision.
People whose misspelled badge has been corrected .. badly .. by hand. (Tip: They can and will print you a new one on site. Ask!)
My favorite: the "We can't read your name because your badge is covered with Greek letters and stickers from the six colleges you went to for undergrad" guy/girl.
People STANDING IN THE MIDDLE OF THE WALKWAY looking at their phone or talking to their friends in a big circle. FIND A WALL.
People who refuse to stand to the side on the escalator, or who stand shoulder to shoulder, making it so no one can get by.
HS students or college students who have never had a conducting class waving a baton to conduct an invisible orchestra - and then buying that baton before they know how to "size" and "fit" a baton.
The Broom guys.
The guy/gal who is having a loud conversation with their bluetooth or with their phone on speaker mode in front of their face.
The guy driving a car whose horn honks .0000000001 seconds after the light turns green (Usually a cabbie).
The people who get to the front of the line at Fuddrucker's/McDonald's/Baskin Robbins/the mall food court and THEN say "What do I want?" when they've been standing in queue for ten minutes.
The people who DO NOT PUT THEIR PHONE AWAY in Lila Cockerell - even when it's dark.
And, my personal favorite:
The person who goes into ANY room, building, or otherwise, takes exactly ONE step into the room, then stops moving and looks around. Never mind that there are people BEHIND YOU wanting to get in. Never mind that there's a ton of empty space literally five steps in every direction. EVERYONE ELSE must stop and wait for you to look around and find your friends. Bonus points if this person does this in a session with double doors - but in which only one of the doors is unlocked, so literally no one else can come in.
