went to Sainsbury’s off Victoria street once,had to go around the back to the service road,a car was blocking the entrance and I would not have got through without scraping along said car,we did try to locate the owner but couldn’t find him/her,eventually Sainsbury’s manager called the police who said to me to go through,i said I couldn’t,his reply was go through and he will sort it,so I got his number and station which he was happy to give and I went through with a bit of a crunch as the trailer t bar scraped the car,never knew what happened after that as nothing else came of it,told management when I got back but they never heard anything either,doubt you would get away with that nowadays though.
