Thankfully, most bar and grills experience are slower at that time ( lunch customers have left, evening / dinner customers have not arrived yet).
And now, sadly a "but" at a bad time....
@Love Never Fails has pointed out that UPS is based in Louisville. It is likely a large shipping hub. This brings in the distinct possibility of a lot of people working shift work. And, UPS evidently has unusual shifts.
Going back to the number of possible bar patrons.... Large numbers of people on shift work can turn the normal customer flow on its head because people have varied days off besides the weekends and shift work means that people have different times for fun.
For example, we start at 0530, so for us, late afternoon is really evening at time for a dinner at a bar and grill. Tuesday is my Friday night. Or, I work the grave yard shift and sleep late. Late afternoon is lunch time for me.
