Woah, wo-oh-oh-oh, sweet love of mine

I was wondering where the postmen meet up before they start their rounds. The post office sounds too ordinary. There must be an office, or something, for the postmen to take their breaks. And what happens if a lot of the houses on their route didn't get mail on a certain day? Does that mean their hours differ just as much as a waiters? Also, why do we have to have skinny postmen? At least give the mildly obease ones the job of driving the van that delivers the parcels. That'd be nice. I guess our government doesn't think that ahead.
