I have been a Tesco customer from as far back as I can remember. I live some way from a store, Morrisons, Marks & Spencer and Asda are all nearer yet I still patronise the store with some frequency, especially for fuel. Today I had the displeasure of shopping in a Tesco store, Hoover Building, Western Avenue, Greenford, UB6 8DW. After buying petrol, I popped into the store for biscuits and bananas. At a self service till, the cost was £2.18. I paid with cash, counting out a ten pence piece, five pence piece and one pence piece. I inserted them then added a £10 note. I did this in order to limit the amount of change I received, hoping for a £5 note and three, £1 coins. Instead, the register churned out a £5 note and lots of change. (The incorrect change only registering 16p in coins not 18p. As I was waiting for the change in coins which were taking some time to finish dropping, a worker standing next to me said, "You used a card; that's not your money!" Initially I thought she was joking. When she then physically blocked me from taking my change, standing with her body and waving her hand before it and called a security guard, I soon learnt that she was being deadly serious. She told the security guard that I was taking money which wasn't mine! There were about 4 people using the tills so it wasn't busy. The previous shopper using the till before me had left some time ago. How could that person's money still be coming out of the register after I had scanned and paid for my shopping? She demanded to see my receipt to prove her claim. Now I am fuming. I told her again that I had used cash and that her allegation made no sense. She wouldn't believe that I had used cash despite my loud protestations. The security guard was asking that I not voice my dissent in front of other customers, not realising that the worker and he were the ones making me feel shocked, overwhelmed, distressed, embarrassed. I couldn't contain my emotions and started to cry. I was being accused of theft! I asked the security guard to instead of speaking with me, to ask the worker why she believed that my change was not mine. He said that he would ask her later. She again said that I had used a credit card! The security guard told her to stay out of the heated discussion. I was now in floods of tears. Why was this worker adamant and more willing to believe that I had stolen someone else's money opposed to listening to me stating that I had used cash? I did not believe that the security guard was handling the situation well. I have never been accused of theft before and certainly have never heard of such a thing in a store as a result of someone collecting their own change. I asked to speak with the manager expecting him to resolve the issue by telling his colleague that she had acted improperly. It was further though inflamed when the manager, Steve, told me that it was quite feasible that the money belonged to the previous shopper! I cried further. I was so pent up with insult and anger. I poured my purchases out and asked for a refund. In just over two years, I will be 60 years old. I am not a young looking hoodlum, who wears baggy jeans and a hoodie. I am producing a feature film to be directed by Gil Junger, director of 'Ten Things I Hate About You. Before Vanessa Feltz and Tricia Goddard, I was the first woman in the UK to host an eponymous TV talk show. The Chrystal Rose Show aired on Carlton TV for 103 programmes. I am a professional individual. How dare the store workers accuse me of theft, preferring to believe that I am stealing someone else's money opposed to the money I am picking up, being change from my purchases? As a black person, this to me smacks of racism. Would the same charge have been levied if I were white and middle aged? Since it happened this afternoon, I have been trying to make sense of it all, but it is hard to make sense out of racist nonsense. Tesco also discriminates regarding the cost of car insurance depending on your name. Do view a YouTube video evidencing that. I have verbally complained to Tesco Head Office plus sent an email to the CEO but have not had a response yet. If the option existed, I would give Tesco 0/10!!!
