An anonymous reader writes: I attend the University of Illinois at Chicago. Last semester my housing arrangements went smoothly. I put down my application fee, and my deposit just fine, got a room for the semester and life went on. This semester, because there was supposedly a large number of students who did not check into their rooms last semester, we were required to make a $100 prepayment, in addition to the application fee and deposit. No problem, I think, I see the university is trying to make a quick buck off people who don't follow through with their plans. Now I do NOT have a checking account, a credit card, or anything. I am one of the few people who do EVERYTHING in cash. I don't trust the banks, I don't trust credit card companies. I also had a trip planned for out of the country, so I get my cash, and on my way to the airport, I stop by the housing office to make my prepayment. They refuse to take cash. They will not charge my university account (so I can pay the bursar or whoever I need to) in cash, and they want a check or money order. Nowhere in their letter did they say that. I fear out of technicality I am going to loose my housing since I cannot get them their money on time because they do not take cash. Is it legal for a state-owned university, let alone any business to not take legal tender?
