- I had an FO grab the paperwork off my lap while I was looking at it once. That kinda bugged me.

- Telling the flight attendant that it's okay to close the door.

- When there's a congested ramp or ground frequency and the FO waits for a 10 second pause before he keys in. Then when he finally gets the guts to push the button he's always stepping on the controller. (That only bugs me when it's the last leg and I want to be done.)
