When You Find A Hair In Your Food, It's Probably Yours
Restaurant cooks know that there's no easier way to ruin a perfectly good dish than to get a hair in it. For this reason, they're super-vigilant about it, and it's time to come to terms with a hard truth: When you find a hair in your food, it's usually yours.
Chefs and cooks wear hats in the kitchen, and some even wear beard covers, with the specific purpose of forming a barrier between their hair and your food. You, on the other hand, spend 15 or so minutes hovering directly over your plate of food while you eat it. If you find a hair, especially if it's on top of your food (and not submerged in it), it's probably yours.
Now, of course, there are some exceptions. If you have long blonde hair and you find a short dark hair in your food, it's probably not yours. If you're eating lasagna and end up tugging out a strand from deep inside its depths, it's probably not yours. But ask any chef and they'll tell you that the in the majority of instances when a dish is sent back to the kitchen because of a hair, that hair doesn't match up with that of anyone who's had contact with the food.
