At the venue where I was playing, the local authorities came in and informed the owner that they were going to be watching the bars that stayed open the extra hour very closely.
Drunks from other bars like to seek out the bars that stay open for the extra hour. And, with an extra hour of drinking time, the police watch for drivers that may have been "over-served".
The place I played closed at the regular time, and I got an extra hour of sleep.
