"You have to eat well and work hard."Oh, and slow down and enjoy life."Everyone's in a hurry," she says with a scolding look.In 1954, Evelyn and husband Elton turned their local gas station into an eatery."He said, we're gonna do a restaurant. I said, good luck!" she laughs.But 72 years later, she's proud of sons, grandsons and more who have employed thousands of local residents at their multiple eateries around Tampa Bay.Son Fred Johnson yes, the namesake Fred says his mother is a must-see attraction at the Plant City location."When she's not here, they're like, WHERE IS SHE?" he says, smiling.You better believe there's going to be a celebration this September.And another one in 2027, of course, when she turns 100.For more on Fred's Market and more, go here.
