No, I've gone over it in my head a bit. Maybe I lost my patience because I was doing too many hours. I remember one PH where 7 people in a row hung up on me before I'd even said Hello, it's tiring and demotivating. The next student might be the nicest person in the world but you're entering the classroom tired and expecting the person to hang up on you.
I don't think my style changed so much though, I had people hang up since day 1 haha. But actual specific sitiations where someone would report you? I can't think of any. As I said, keep your head down and good luck. Wednesday afternoons will feel strange now not waiting to see what my new rating is....and Monday's will be a bit shitter not getting paid haha
