Just to name one thing; meetings that start 5-10 minutes late. For them it's normal, because they're in the room, or walking to the room, or at least aware as to why a meeting is starting late. To me, it's 15 minutes wasted, and there's no communication what's going on.
We're getting better at it tho; or at least, I've lowered my expectations of them. I know that I will be left out of meetings frequently, I know that every meeting will start 5-10 minutes late.
That said, I love working remotely, although I would prefer to find a team that's used to it.
