Tesco Cafe in Merton - Phone Number, Reservations, Reviews

my name is Giuseppe and sometimes i shop at the tesco , afterwards i relax with a coffee at the. bar above. this time it was not a moment of relaxation as I asked for a double decaf macchiato and it was given to me in a small single espresso cup with some milk foam on top, to which I told the girl and a another barrista that double coffee I preferred to have it longer and in a bigger cup but was told flatly that this was their double coffee and they had no intention of changing it. I didn't have the coffee and I gave him the cost of the coffee that I had already paid, a bad service done by unprofessional staff, I think I will hardly return
