Trust me it took all of my will power not to pack up my shit, tell them I'm sorry that their parents were so cruel to have kept them instead of having an abortion when they found out they were carrying the spawn of idiots and then ask the girls at the front desk to boot them out. Just I really needed to use a computer.
All I can say is bring back the cane. Some kids need to know that bad behaviour is not acceptable and yelling at them doesn't always get the point through their chemically polluted brains. A good old fashion flogging or even public humiliation might shut them up.
