So says Australian recruiter Greg Savage in a viral post from 2011 just now making another round on click-bait sites:
In recent years it seems that a meeting set to start at 9 am, for some people means in the general vicinity of any time which starts with the numeral ‘9’. Like 9.30 for example.
People drift in at 9.10 or 9.20, or even later. And they smile warmly at the waiting group, as they unwrap their bacon sandwich, apparently totally unconcerned that others have been there since five to nine, prepared and ready to start.
It’s simply that some people no longer even pretend that they think your time is as important as theirs. And technology makes it worse. It seems texting or emailing that you are late somehow means you are no longer late.
You are rude. And inconsiderate.
Savage takes a hard line where few others would in some cases. For example, he hates that people arrive late to dinner parties, but anyone who's hosted one would really prefer people not show up exactly on time. And he may not fare well in cultures that have more flexible views of time, like much of the Middle East. If someone sets a 3pm appointment in Mexico, as an English-speaking Westerner it might be helpful to (tactfully) clarify what cultural effects will act on that appointment time, or you might be waiting for a long time.
