Clubs, Pubs and Parties: Most importantly NEVER leave your drink unattended, NEVER accept a drink from a stranger or recent acquaintance. Drink Spiking -- the act of covertly adding chemicals or drugs to your drink -- is not unheard of and the consequences speak for themselves. Similarly don't leave your cash and valuables unattended. Be aware of your alcohol consumption, try not to overindulge and not be able to safely make your way home. It's possible that someone may be watching and assessing how easy a target you'd make.
