How old are we talking? When me and my sister were at uni everyone got drunk regularly. I'm 46 and she's 41.

Then point it out to someone higher up, or the police.

>> I have loads of free stuff from China which is good enough for what I need, but not what they advertised, so they pay me 100% refund, and the postage costs too much to send it back so they just let me keep it. For example, if you want a 12V 4A supply, buy a 12V 8A supply. A Chinese amp is about two normal amps. You can get 4A out of it, but when you tell them it can't do 8, you get it for free.

You buy a couple from 25 different sellers.

Then get each member of staff or student to buy one each.

Or use Ebay, I can see 40 people selling those from £60 to £100. And more at a higher price.

>> > Most of the stuff we buy isn't cheaper on ebay anyway.

You use one at home or in a gym.
