profit margins

Interesting fact:

If you spend $100 at a restaurant, the server gets an average of $15-20. The restaurant itself, on the other hand, makes a paltry profit of five bucks.

Even worse, turns out if you spend the same amount on groceries, the store makes even less, only two dollars, in profit.

Hmm.. Selling food is harder than I thought..
