Was in two hours early for one consignment and six hours early for the other and back out again, tipped, signed and away in 15 mins. Then again we’re (my company not me) in there daily and its often a few pallets rather than bulk load.
Then got into Ocado over the road early after, and was out of there in 15ins too 
None of it really mattered, still had a collection in Atherstone but it meant I could have a longer kip!
