I would like to know how to say 'stubborn' but I would first like to explain the context: I was negotiating a price discount for a damaged item in a store, but the store manager refuse to make any concession, even if it was obvious that he would never sell it. I wanted to tell him that he was stubborn, but there are many words in the dictionary, and I did not want to use the wrong word. I wanted to politely say that he is stubborn, not insult him. For example, in english, I would have used the word stubborn, but not pig headed. thanks very much for your time and help
