I don't quite understand why urban areas seem to have Post Offices every mile or two.
Are they in different Zip Codes?
During my days of working in San Francisco it became clear that some Post Offices became overrun at different times of day due to all the office buildings on different schedules. One Post Office would be jammed and one about three blocks away would have a very short wait. Of course give an hour either way and their lines would be just the opposite.
One of the local street luminaries would make good money by standing in long P.O. lines, holding a manila envelope and offering to sell his place in line when he was about the third person in line. If it was a busy time, he would then go back to the end of the line and start over. He always had a smile and dressed flashy but well.
