Yea when I worked for Borders they wouldn't let our standalone store close early unless we did less than $200 an hour for several hours AND there was a state of emergency. Basically it had to be too expensive to leave us open.
When I ran a Borders in a mall, we had to close once because the mall closed-I was on the phone with my district manager explaining I sent everyone home while the security guard waited to escort me out because we were literally the last people in the mall, and my district manager asked why i couldn't have had people stay and alphabetize.
We also were not allowed to ask people to leave even after closing. Mall Borders was next door to a Cheesecake Factory, so people would wander in and browse rather than hang out in the mall hallway or in the waiting area of Cheesecake. One Christmas Eve we had people "browsing" for over an hour after we had officially closed. My coworker finally went over and told them point blank if they weren't buying anything they had to leave, and the husband fucking screamed at us about it. They did finally leave, but seriously...people are the worst.
