I have a strong dislike of people who can't manage time properly. This includes:
- being constantly late, all the time, everywhere. If I tell you to meet me at 1:30 it means 1:30, not 1:45, or else I would have told you 1:45. I don't care that you couldn't find a parking spot or that you got lost on the way. I also had to make the exact same trip but I accounted for such incidents and I was on time (and usually 5 min. in advance)
- not being able to give a proper estimate of how much time you need. Like I'm waiting for you to finish your call so that we can go to lunch, and you tell me "2 minutes". 20 minutes later and you tell me "two minutes" again, and 15 minutes later and you're done. Well you suck. Why tell me 2 minutes? Why not tell me 30 minutes so I know I have time to go back to my desk and and do some stuff? Worse offenders are probably waiters who tell you "5 minutes" for a table, knowing full well it will take 15, but hoping that by saying 5 and not 15 you'll stay. Well guess what? I will indeed stay 15 minutes but will likely never come back. Had you told me 15 min., I would have stayed also but I would not have been mad. And sure, it's difficult to estimate, but why not err on the side of caution and overestimate it? That way there is a chance I will be pleasantly surprised.
