Every time you go to the cinema, there are people standing up to leave as soon as the music starts to swell in a "this is nearly the end" kind of a way. Every time you go to a gig there are people leaving when the band first say goodnight, as if they've never heard of encores. Last night the gf and I went to the NEC to watch horses jump over stuff, and again people were leaving as soon as we got a vague idea as to who was going to win the last event.
What's the rush? Why risk missing out on stuff at the end (extra bits in films, awesome encores at gigs and whatnot) for the sake of getting out five minutes earlier? Besides anything else it strikes me as a bit rude, really, to leave before everything has officially finished.
Is there some reason I'm missing?
