I have been tutoring two year 9 kids (a brother and a sister) at their house 6 days a week for two hours for the last nine months. Now, I felt that the pay was too low compared to the hours I spend there. So, I wanted to take up jobs elsewhere. I didn't wanna tell them that the pay was the issue, because their father was not a decent person and would somehow make me stay at his place and tutor his kids. So, I told them that I had family issues and wanted to leave within ten days. I discussed this issue with the guy and told him that my problem was family-related (implying that I did not want to discuss my problem with them). The guy was not satisfied because apparently to them I was a gem of a tutor (in terms of tutoring ability), and he said I couldn't leave because his kids would be hurt, that they have exams coming up in four or five months, that he considers me to be a part of the family, that he wants to speak to my father about the issue, that I couldn't leave my tutoring assignment and leave alone, etc. etc. He wanted to know about my problems and I tried my best to close off the matter with a resounding no. I couldn't actually say a 'resounding no' because that's not how I normally deal with the parents of tutees, but I told him that if I start to negotiate with him in a professional way, and by professional, I meant like a proper businessman doing the deal and no emotional baggage in the way, then I could say a lot of things he wouldn't like. And then he started to verbally harass me. (I can't write down the actual words because of physicsforums' policy on slangs.) He went on to say he could make my life a living hell, that he could monitor every second of my life (This guy was a colonal in the army), that he could finish me once and for all. And then he said he'll speak with me tomorrow. How much madder can someone get?
