“I am the On Site contact for CBS Sports Network that is at the Scottrade Center in St. Louis.

I had to write about your driver… he was lovely, professional, efficient; and these days it never seems to come out enough when someone does something right or well.

He called me in advance to confirm the drop off location. When I chatted with him saying I wish our office could have pushed the time back until I was on site… He said, no problem and he was there at the agreed time. He set up quickly, was professional, got us set up and headed on his way. I will keep your info on file for future trips to St. Louis because of him.”
