Yes there are people who are just disrespectful of our time. Has driven me crazy in the past!
It’s also true that some cultures have a more fluid sense of time — where the emotional connection of the present moment - and bringing that present meeting to a natural close— might override the next meeting’s need to start on time.
And everyone within that culture offers a level of understanding To one another. That’s not our western culture of course. But….
even In NYC, there’s a built in 15 min leeway - where no one gets too freaked out about a slight delay in a meeting start time — and that leeway allows for subway mishaps or traffic jams. We’ve all been there.
Also: does anyone show up to a dinner party exactly on time? It’s a cultural thing, right? No one expects everyone to arrive promptly at 7.
I’m not saying to ignore someone who’s clearly disrespectful.
I’m just suggesting that there MIGHT be other possibilities (apart from disrespect or mere selfishness) that could be at play, depending on where that person is from in the world. My favorite provider almost always ran 30-60 min late; I came to accept it bc of his perception of time.
For me my life has become less stressful when I make room for other possibilities beyond “he’s a selfish prick.”
