AnEver wonder about the impact that supervisors have on the success of a hospitality company? Here is an example: On Restaurant Row in one city, one family restaurant has had 12 different busboys in two months. In the restaurant next door, the food is superb one week and terrible the next. The bar on the corner cannot find a decent bartender, much less keep one. Across the street, one restaurant had a near-riot in the kitchen resulting from an argument between the cooks and servers. The Italian restaurant two doors down is losing customers steadily because its service is so poor. But the oldest restaurant on the block is packing them in night after night, with staff who have been there for years.
