I recently attended the Intel 2015 convention at the Venetian, Las Vegas, Nevada. I was shocked to learn, that a number of security guards haven't even given a relief to go to the bathroom, let alone to go home on time at the end of their shifts. Not to let them have water and a snack with them also pretty inhumane. You might provide a good service for your clients, but are you sure, your company is in compliance with the Labor regulations for your workers? For these reasons I'd give you a zero rating, if it was available.
