Here's another difference between a traditional Publix supermarket and the chain's new GreenWise Market that just debuted at 2403 W Azeele St. in Tampa: the employee appearance code. Male workers can sport long hair if it's kept in a pony tail, grow closely cropped beards or goatees, and wear ear, nose or eyebrow rings if they aren't excessive. Publix wanted to be sure workers fit the scene and didn't want tougher standards to scare off prospects with knowledge and passion for the natural/organic foods sold at GreenWise. The changes stirred some envy at traditional Publix stores. But workers there should know Publix's recent decision to allow store managers to shed their company neckties started as a GreenWise test in South Florida. "We didn't get one complaint in 14 months," said company spokeswoman Shannon Patten.
