Another vending machine this time, by iced tea makers Bos, created by Radar Asia Pacific, the vending machine gives out free drink, but to get the drink you tweet the drinks twitter page, @bos with the hashtag #BOSTWEET4T and the free drink is yours. Though if I tweeted them I wouldn’t get anything because cleverly (and to reduce fakes!) they used the location settings from Twitter to make sure it only works for those nearby. It also shows their name on the LED strip on the machine, making it a little more personalised. I wonder if there was anyway to choose the flavour you got?
