We have a Irish tavern in the middle of town. Once a year the traffic stops to honor an important Saint. The numbers of Irish in the area are sparse, but we had a lot of people dressed in green. The beer started at 4PM and the live music went to 11PM and by midnight every one disappeared.
As the evening progressed the short line became a problem.
But the long line was even worse, I think people thought it would be cleaner in the tavern.
