I went to an all girls school and we had some of the most horrific teachers - you had to wonder why they even went into the profession. A physics teacher who wore a purple velvet suit (pretty sure it was the same one every day) that would lean far too close to you than was comfortable or would come and watch us play tennis and netball in very short skirts (we learned very quickly not to bend at the waist!). He was sacked for having it away with the 6th form pupil.
Latin teacher who would just shout at you if you got something wrong and slam his hand on your desk. Many a time remember jumping out of my skin as he would wander around reading over your shoulder and then suddenly 'bam!' this hand appeared in the middle of your work.
a headmistress who was sadistic and took great pleasure in lecturing the entire school about every deadly sin you could think of and us sitting there on the wooden floor of the school hall, crossed legged, getting splinters in our btms and waiting for her head to explode with rage

Having to go and buy tripe for my Nan from the local butcher....still gives me a queasy tummy. Didn't know what it was at first until my mum explained it to me and I used to run or cycle home as fast as I could with it at arm's length when I knew its source....pigs feet too
hand me downs from my two older sisters and an absolute witch of a grandmother (not Nan above) who just to call all us three girls 'fat' (we weren't by any means) and if we wore make up (even a scrap of mascara) used to comment ' no wonder girls get raped these days....' My dad heard it once and nearly blew the roof off the house.
I did like the school milk bottles though, feeling rich when you had your pocket money and you knew it would cover all your sweet and comic related purchases for the whole week, not caring about what brand your trainers were or who's got the latest bit of technology as you were too busy building dens, my own sewing machine when I was 11 and the after lunch naps we had in kindergarten
