I'm going to pretend I can't hear what the costumer is saying and hang up the phone.
Why would you hang up on them?
Because I don't want to talk to foreigners.
It's not nice to fake an impairment like being deaf. That being said, it's understandable to feel annoyed when dealing with customers sometimes.
How am I faking it? My ears are messed up.
You just said you would pretend to be deaf. Being deaf is not something to joke about. A lot of people get frustrated when they lose their hearing.
