Is it unreasonable to use the right pronunciation back to someone who uses the wrong one? Aldi is pronounced with an A (Al-Dee). Audi is pronounced with an Ow (Ow-Dee). Omega watches have a stress on the O, not the Me. I never know whether to say the word correctly or just go along with the wrong one to humour the person. When it's someone's name it's simpler as they introduce themselves with their chosen pronunciation, like Renée (pronounced Ree-nee for old ladies up North).
