I recently visited Tesco at The Cheetham Hill Shopping Centre during snowfall and forgot to bring my Tesco Clubcard. I requested assistance from a staff member named Sami Ullah to key in my Clubcard details using a picture, but he refused. Instead, he suggested I complete my shopping, return the next day with my physical Clubcard, and claim the discount then. When I mentioned that I’d prefer not to shop at Tesco under these circumstances, he simply responded, "That's fine if you don't shop here." This is incredibly poor customer service. I felt undervalued and disrespected. I have decided not to visit Tesco anymore. There are plenty of other options like Lidl, Asda, and Aldi, where they genuinely care about their customers and treat them with respect.
