When visiting my local Tesco, a few days ago, I was approached by the store manager and asked to leave. When I asked why, I was told I was banned for shoplifting. I asked for any proof of this claim and again, was asked to leave the store. I left, promising to take this up with their Head Office, which I did by email and letter. I received a response from them thus: "you have been monitored for the last few months and as a result, he had banned you from entering the store." I find this a mystery as I've never been accused of shoplifting before, nor have I stolen anything.
