When I was about 18, I went to work in the Bank of New Zealand - the job was mainly the Manager's typist. Sometimes I also worked on the bookeeping machine, debiting and crediting to and from clients accounts. This was before computers of course.
I just thought of something funny! I had an algebra exam, marks - 3%. My maths teacher was an old dragon ( well, with me anyway, I was so useless)! The 3% was for neatness, and spelling my name correctly. Zero for the Algebra!
I worked as a stand-in teller in the lunch breaks, which was actually a very busy time, as a lot of the local businesses did their banking between 1 and 2 pm.
One day, there was my old dragon Maths Teacher standing in my queue! Oh dear... I had hoped she might change to another teller before she reached me, but no - didn't happen!
There she stood in front of me.... looked very puzzled, and while I was checking her cash deposit, she said "How in Heaven's name did YOU ever get a job as a bank teller"
I smiled and told her " we have REALLY Excellent tutors, but please don't interrupt me while I'm counting your cash, sorry, but I'll have to start again. Her face went very red, (just as it did in the classroom) but I started again.... really...really...slowly! 🐢🐢
Many years later, I met up with her again, when I was a "mature student" at Teachers college. I was doing my first teaching practice with Juniors, and she was one of the overseer's. Fortunately she wasn't doing Juniors, just as well! I didn't know she was at the school until I saw her in the staffroom at morning tea! Oh Noooo! I grabbed my cuppa and promptly went outside, and walked around the playground with some littlies. I don't know whether she saw me or not, but if she did, I don't think she would have recognised me anyway, all those years later.
