Would you buy a 'suspended coffee' for someone in need?
The daily trip to a local coffee shop may give you your caffeine fix - but thanks to a new scheme, it could also give you a chance to do a small good deed.
The idea of "Suspended Coffee" is simple: When you buy yourself a coffee at a participating cafe, you also pay for a second one - which can then be claimed by someone who cannot afford it themselves.
They don't have to "prove" anything to claim one, but the scheme relies on the good faith of everyone involved.
The movement has been growing in popularity since it began in Italy several years ago, and has already been embraced by hundreds of coffee shops around the world. Now Starbucks has announced it will soon be adopting a version of the scheme.
BBC News went along to one of the shops taking part: Coffee7 in Forest Gate, east London.
Stop/Start is a new series of video features for the BBC News website which follows new trends that are beginning just as old traditions are ending.
