Here is the unusual way to get a free gin and tonic from Greene King pubs in Sussex

To mark World Gin Day, the chain is giving away one free drink per customer on Saturday, June 8. The only catch is that they have to bring an orange and show a team member at the bar to claim their reward: either a 25ml measure of Beefeater Blood Orange or Pink Strawberry gin, served with a Schweppes tonic. A spokesman for Greene King said: "Everyone loves a freebie and World Gin Day is the perfect time to treat our locals with a refreshing summer drink. “Our giveaway for World Gin Day is just one of the exciting activities happening at our pub this summer for Greene King’s Great British Summer Social, which will see more than 1,500 events happening at pubs nationwide. “We can’t wait to welcome our locals in for a free G&T this weekend and to experience the events at our pub throughout our Great British Summer Social – let the celebrations ‘be-gin’!” Here's the full list of participating pubs: Chichester and Bognor Regis: The Old Cross, North Street, Chichester Trents, South Street, Chichester The Martlets, Aldwick Road, Bognor Regis Worthing, Shoreham and Littlehampton: The Cricketers, The Green, Southwick The Waterside, Ferry Road, Shoreham The Swiss Cottage, Shoreham Road, Shoreham The Thieves Kitchen, Warwick Street, Worthing The Broadwater, Broadwater Street West, Worthing The Golden Lion, The Strand, Goring The Mulberry, Goring Road, Goring The Sussex Yeoman, Palatine Road, Goring The Lamb Inn, The Street, Rustington Mid Sussex: The Railway, Station Road, Burgess Hill The Star, The Broadway, Haywards Heath The Burrell Arms, Commercial Square, Haywards Heath The Dorset Arms, High Street, East Grinstead The Station, New Town, Uckfield Horsham and Crawley: The Anchor Hotel, Market Square, Horsham The Crown, Carfax, Horsham The Sussex Barn, North Heath Lane, Horsham The Old Punch Bowl, High Street, Crawley The Air Balloon, Brighton Road, Horley The Snooty Fox, Haslett Avenue East, Three Bridges Eastbourne: The Rodmill, Rangemore Drive, Eastbourne The Mill, Willingdon Drove, Eastbourne Bexhill: The Rose & Crown, Turkey Road, Bexhill Visit greeneking.co.uk for more details.
