Might be something to do with LA (and possibly other large urban/metro areas) but possibly something more to do with 'school'. Even at a university level, people are still kids or young adults, don't have many connections, don't really understand the impact of their actions, reputation, etc. ) I saw this sort of "yeah/maybe/cancel" behaviour amongst some portion of peers back in my university days, but even then, it wasn't everyone, or even most people in my circles. It was known poor behaviour then. We tolerated things a bit more because... no mobile phones, no email, etc. If you weren't there, you weren't there, but often didn't have a good way to let someone know you had to cancel ahead of time (but you'd check your answering machine timestamp to verify!).
