And just how do you propose that a restaurant open to the public 'control' the idiots that break out in fights? They can't profile the customers. Armed guards would be considered racist by the usual hustlers that would point to other Denny's locations that don't have armed guards.
It is not up to a legal business to control society or patrons. If the people of the city can't control themselves the police should be handling the problem. Instead the police encouraged the Denny's to close during overnight hours.
Forcing a legitimate business to close because the people are animals and the police can't keep the peace is not good for the remainder of this city, or the area for that matter.
I've heard that McDonalds gives police free food as an incentive to have them hanging around the store and patrolling the parking lot. Maybe it would work for Denny's.
I propose that nobody eats there and it goes out of business. I wouldn’t eat anywhere I didn’t feel safe. Apparently it isn’t possible to operate a restaurant in that section of town. That’s just a cold hard fact.
