Went to Morrissons at Sittingbourne the other week. Hand ball 20ft, 5 hrs on bay, sat in cab, keys in the ignition. Guess what, no one died! Would go there 10 times rather than Tesco or Sainsburys once. The best system was Geo Logistics at Thurrock. No red lights, just an IBC full of concrete placed in front of the truck. Keep the keys and do what you like, you aint going nowhere
