The restaurant did not last long as I expected from the very beginning. I had to repeat my order four or five times till the (most stupid) waiter (I have ever seen) understood what I really wanted. I wanted Chicken Tikka; and she of course repeated it as Chicken Tikka Masala! Finally I talked directly to the cook who understood what I meant.
Yes, there are cases where waiters misunderstand me. Once in Chennai, probably around 1997, I got Pepsi cola when I ordered "Vegetable Noodle Soup". But that experience was sweet rather than sour, at least, for me. I still remember the face of the waiter who opened the bottle with pride. It took me some time till I understood why he brought me a cola.
