Cargo sales,
When my dog came into Gatwick in a cargo crate moons ago it could only be picked up by the Quarantine company. I went to the cargo shed to just check everything was OK to be greeted by shouts from the cargo guys on the top of boxes telling to look out there was a loose dog !!!
I put him back in the repaired crate and waited under an oath of sworn secrecy !! for the quarantine company to arrive.
