A bit random - and in no way a teacher bashing thread! I was just inspired randomly by a thread about whether people make sure the sink is dry after use.
I had an absolute hag of a home economics teacher - who one day had a right go at me after I had washed up all the dishes. She lifted up the wash basin, and there were soap suds on the bottom of the basin. She got angry at me for it, and made stay behind and wash it until there was not a soap sud left. I was then late for next lesson. I'm still indignant about it, she was a fucking loose screw.
This was only 10 years ago!!!
