FLOURISSANT, MOPick'n Save stockboy Joel Melcher said Monday that his overexposure to groceries has destroyed his taste for food. 'When I first started working here, I thought, 'This is awesomeI'll be able to bring bags of food home from work every night,'' said Melcher, who receives a 25 percent discount at the store. 'But now, being around it all day long, at the end of the day I can't even stand to look at frozen food, baked goods, meat, dairy items, or produce. Makes me sick just thinking about it.' Melcher has vowed that, when he gets a new job, he 'will never set foot in a grocery store ever again.'
