I was a receptionist for 2 years in a hospital. On voluntary basis but still. The thought of answering the phone or having a line of people there waiting for me was absolutely terrifying. The first few weeks that even made my stutter worse than on average. But what I found out was that it wasn’t all that bad. Generally people were pretty patient, unless they were already upset about something else but that’s not my problem. On the phone it was a little bit different as they can’t see you so when I was silent because I was struggling a bit the person on the phone would often ask me if I was still there or what was going on with the connection, but then I just apologised and explained myself and they were fine with it. It took me a while to get comfortable enough with using the phone to not dread it completely but knowing that most people were nice and understood was really helpful. And sometimes you have a dickead on the phone who doesn’t want to wait and hangs up. But again, that’s not my problem. They came to me for help and they refused to be patient.
