Dave Thomas was a franchisee from the mid-1950s, and developed the rotating bucket sign that came to be used at many KFC locations.[28] Thomas reported that Sanders’ fried chicken was a “sensation” from the first day he offered it in his restaurant, with queues lining outside the door.[29] He was an early advocate of the take-out concept that Harman had pioneered, and introduced a bookkeeping form that Sanders rolled out across the entire KFC chain.[22][30] Thomas sold his shares in 1968 for US$1 million (around US$7 million in 2013), and became regional manager for all KFC restaurants east of the Mississippi before founding the Wendy’s restaurant chain in 1969.[28][31]
