Oh it ticks me off to no end when people take all my credit. I do enjoy working hard, and I love working with my hands, but gosh darnit, ask before you take all my credit.
As for school, I see it all the time and get very odd looks when I punish a student for cheating. But then, the school takes money from the kids parents and the kid is back in my class. But... I have a rule. Cheaters, copy cats get a zero in my class. So at the end of the term, when all the grades are in, I announce their grades, and put them on the wall with names and student number so everyone can see the grade. Still, it doesn't matter much as again, parents will just pay extra and their kid will pass.
And it pains me to see this as I teach many hard working and wonderful kids. Many of these kids want to go abroad and study and work, but in order for them to do something professional abroad, they must go back to school and pay more money so that way the foreign country company will know they actually know the work.
