When my school confiscates something from you, it only gives it back at the end of the next day, and always gives it to you in a bag, while charging you for the FREAKING UNNECESSARY bag! Everyone (including me) is bound to have something confiscated, someday...
Also, most of the teachers refuse to receive homework online, even though the school encourages you to use it. And I haven't got a printer, so it's very inconvenient for me to get something printed.
EDIT: X-Post. My school doesn't accept cash for food at all - You can only use their stupid system that requires your fingerprint. It's ridiculous, you can never see how much you have, and taking away cash is completely pointless.
