The best restaurants serving Turkish food in Maida Vale City of London, Westminster London

I went inside the shop to buy a birthday cake. There was another customer waiting already there. After approximately 10 mins the owner arrived, and serviced the customer very slowly. In the meantime, there were more customers arriving at the shop after me. I was the only one who was wearing a mask, and others seemed not to take covid measures. When it was my turn, I start asking question to the owner about the various cakes there were in the window. I asked a couple of questions, but he ignored my last question and started chit chatting with other customers (not in English) that have just arrived. I explained I was in a hurry and then he rudely replied to me asking me to decide quickly. When he answered to my question, I chose the cake, paid and left. The cake was tasty, and of good quality but I am not returning back after such a rude/poor behaviour.
