I'd like to nominate Forge Bakehouse as they are running a pay kindness forward scheme where customers can pay a little extra so someone who can't afford to pay but still need food can access it.
They have extended this to providing free kids lunches which can be collected as well as partnering up with with St Mary's church on Bramall Lane where they run a Social Supermarket. Forge Bakehouse will start supplying bread which is hard for the social supermarket to get hold of as usually it's low quality or going out of date.
