✱ 8 – French Fries
French fries in restaurants are very tasty. However, you’ll want to think twice about eating them again. The oil that is used to fry the fries is reused. Therefore, the pan never gets cleaned out. They just keep frying fries in the same oil that was used for the patch of fries before that. And they will keep reusing it until it turns dark brown. Not sanitary by any means. The same applies to chicken wings.
