In exchange for discount on drinks, Staff at Time Bar entices its customers to surrender to them empty jars for their own use. The empty jars are actually used in lieu of glasses to hold their best-selling cocktail, The Mojito. The idea is to encourage people to reuse jars rather than throwing them away.
The mojito was chosen to promote the scheme because “it’s the cocktail that looks best in the jars”, but customers can choose any drink.
“All our glass waste gets recycled and our head bartender has got an allotment, so he takes all of the food waste to put back in the ground.”
