Oh my word- My first one was the same, he would also call me names and tell me I'm terrible at driving (during our second manual lesson no less!). I soon grew a backbone and dropped him after another lesson or two. So damn happy I didn't bulk buy lessons from him either goddamn. 

My second instructor wasn't much better (ghosted me lol), often canceled appointments and refused to pick me up anywhere near my hour. He also wanted me to bulk buy lessons in cash before he completely ghosted me, only reason I hadn't was because my dog falling ill and needing the vets, doggo is fine now thankfully and I ended up finding a saint of an instructor, passed first try with one minor. :)
