Our security was very surprised last night to see this when I asked them
I think our security are supposed to have a good idea of what goes on both in our site AND immediately outside. This includes people parking/unloading/waiting too close to the gates, items left on the sidewalk (this example), broken glass in the roadway (last week)
Please explain to them that they are our 'eyes and ears' ... if they see something going on outside they should inform you (who will inform the managers)
