The best restaurants serving Other cuisines food in St Michael's and Wicksteed Kettering East Midlands

I had a bad experience at this costa today, I was in line and the people in front of me allowed me to go in front of them as I had cold food and they all were waiting for their hot food. When I was served (by the manger I assume) she was very condescending and tried to explain to me how a que worked (sarcastically of course) and then when I later purchased a panini she undercooked it by 3 minutes (as a costa worker myself I am aware of how long they go under for) I then return the panini without a refund and left. Just because she was older than me doesn’t mean she should have spoke down to me, I hope her service improves so she can be an example to her staff, and not an example of bad customer service
