no bans i know of.
Im banned from OConnors in Widnes i got sacked by that nice Mr S OConnor for being off route 
I was once banned from United Wholesale on Queenslie for refusing to drive with pallet set in the middle of the van 
Finally I agreed to drive after the guy who loaded the stuff agreed that if it will tip over, I will come back and he will restack it himself.
Sadly I am too good driver and as I drove carefully the pallet stayed intact. Yet on my return he told me I am banned anyway
But it turned up that I was the only agency driver who can drive and who knew that CD Player is not the best place to place your tacho chart in etc. who was accepting the jobs from them on regular basis and knew all the jobs and knew all the mates, who liked to work with me, as I was working instead of moaning on handball, so they were begging me to come back. Sadly, I was not accepting the jobs on the week rate, so I was going there only on saturdays if I needed some extra pocketmoney
