I have experienced up to 3 times that on Friday evening the bar closes at 2:00 AM and a porter sends everyone outside in a very unprofessional way, including swearing words.

It is effective because he manages to chase around 150 guests to the lifts and lock the door within 7 minutes.
Some are so overwhelmed that they forget their coat and cannot go back.

I don't think a hotel can handle its guests that way.

It also sometimes takes a very long time at the bar before you get your drink while they are quite expensive.
