Scott Reeder:

A while back, I showed up at the post office a half-hour before closing time and got in line to mail a package.
An officious man came up to me, pointed at the clerks working behind the counter and said, “If you are still in line at 5:30 p.m. you’ll have to leave because I’m not going to pay those people overtime.”
So I left the post office and drove across town to FedEx.
I can’t imagine standing in line to pay for groceries at the supermarket and being turned away out of fear that maybe I’d still be in line past closing time.
To be sure, I’ve had my share of annoying experiences with private businesses.
