Yes JeSuisPrest has it, I think.
Occasional lateness I can cope with - in particular the "oh god I just stopped for petrol and now there 's a massive queue and the card machine has crashed" type of lateness, as long as people let you know what's happening. This has happened to me in the past and I appreciate a bit of give and take. I also have a friend with OCD who I know really struggles and I tend to just take a book and wait for her, or we arrange things that aren't time dependent (e.g. pop over for a DVD rather than go to a film)
However, the category of people who are chronically late because they never realise that the endless errand-running en route places affects their timing, or who simply don't care and think you should be more relaxed about stuff drive me bananas.
I had a work colleague who was like this and we frequently had to travel together. She doesn't drive and I lost count of the amount of times I would be left sitting in my car in front of her block of flats, waiting for her to be ready to get going. We'd often have to drive to the airport then fly, and after two times where we had to run and only just made it to the plane (one of which only happened because while I was waiting I paid to upgrade us to fast-track security), I decided I wasn't going to do it any more. Her attitude was "That was FUN! Like in a movie! HA HA"
I told her what time I'd be there for our next trip and what time was the absolute latest I'd leave. Reiterated it again before I set off for hers, then again when I was outside. She still didn't appear and so I phoned her to say I'd be leaving in 10 minutes. Yes yes, fine I'll be down in two ticks. 10 minutes later she still hadn't appeared so I simply left.
She was absolutely FURIOUS that I had actually gone without her.
She missed the flight, couldn't come to the meeting and while I was there I had a revelation that it wasn't just the flight thing - when I was there alone I also didn't have to make any random detours into shops for things she'd forgotten/wait for her to redo her makeup in the loo/get changed/take a phone call etc. etc. I simply went to the meeting, did what I needed to do and returned to the airport. It turned out that I was done so early that I was able to get bumped to an earlier flight home.
My boss couldn't figure it out and I do regret not being more blunt with him about it. However I did tell him that it wouldn't be possible for me to travel with her any more and I swear my blood pressure dropped 20 points. Miraculously she always managed to get herself to the airport on time from then on, and simply meet me on the plane...
Moral of story: don't just hang around waiting for the late people - crack on with your day and either they'll learn not to treat your time as less important than theirs or you'll shed yourself of a CF acquaintance.
