OMG, I cannot stand something like that happening. (I'm referring, of course, to DR Ron's restaurant adventure.)
It isn't even just my being early or late, or someone else's being early or late. It's the whole out-of-sync quality of the experience that completely blows it for me.
That food line would have totally killed it for me, too. And I can't stand being the last one with food and being the only one left eating, in any event - doesn't matter what the circumstances are. I, too, would choose to just blow it off and wait till later, however hungry I might be.
