Quick job for UK Mail, take a trailer load of mail to the RM office in Hounslow and then bring back empties. No problem, turned up at 09:45 only to be told by security that i have to wait outside till 10:00 as that is my time slot. Had a quick break and on the bay, unload, load up and ready to go. Have to admit that some people at RM make their job more difficult than it is, had a cage full of mailbags so asked if we could swap. I give them the full cage and in return i get one of their empty ones, 'no can do, you have to unload it'. Surely that makes more work when a simple swap would be enough. Back in the yard and had to park up all the rigids and tractor units in the warehouse as this being Slough things might go astray, so I was informed.
