4. Food safety
Sad to say, many of the employees hired on to do the cooking, food handling and prep don't have the necessary training or food safety education they need to do it right. Not their fault — the companies often don't offer training because these restaurants have such a high turnover rate. On any given day, you could have someone preparing your hamburger who didn't wash their hands or who was playing with frozen raw meat right before they manhandled your bun. Save yourself the food poisoning.
