I spoke with David, the manager of that facility. He stated he was aware of this very situation, and it happned the day after the robbery. He said his security was a bit overzealous.
He also stated that should another problem arise, to contact the on duty manager and if that didn't work, have them call him
He also said, some of these expediter vans are not marked, so he, and security, have no clue if indeed you are an expediter, if not marked.
Seems this was a one time happening .... we can hope!
I followed up with my Flying J/Pilot rep as well and I was assured the same thing. No change in policy and that they appreciate and welcome the van business.
