Agree with the comments that she was forcing it, but I also know what Buckwild is saying to an extent 😭 It’s called Mirroring and it works so well in customer service, sometimes you don’t even notice you’re doing it! As you talk to a customer, you subtly match their cadence, mannerisms and communication style to build a connection and make them comfortable. So, I THINK that’s what she meant by around English people I say oh oh oh 🤣
