Sweetie, did you ever watch COPS on TV or any of those "dumbest criminal" shows on what used to be Court TV? Real footage of real cops arresting real people who do not want to be arrested, sometimes when they are drunk or high on meth or something?
And in a job where you are never sure how you are going to be received when you talk to somebody, having a safe place where you can have a cup of coffee is an island of comfort. Patrolmen are the first ones on the scene for auto accidents, domestic violence, lost children and all manner of people in pain. I say give them a break.
They are training to be able to defend themselves using only their body as a weapon. As well as trying to maintain a good physical condition.
Then they have donuts as a special little treat for their persistence! Mmmm donuts
