Social media
Popularly, Lewis is known for being the owner of the Twitter account '@johnlewis', to which hundreds of users from across the world mistakenly send tweets intended for the British department store John Lewis or the American politician and civil rights leader John Lewis. He has been described as "the most patient man on the internet" by British social media users for redirecting with humour mistaken requests and messages sent to him, especially around the Christmas shopping period. The department store sent Lewis a gift set as an acknowledgment and a thank you in 2016 for the inconvenience caused to him. In 2018, Lewis was featured in a Twitter Christmas ad with the hashtag #NotARetailStore.
