What a bunch of useless chit-chatter in this thread. It's sound advice.
If you're an American, it's almost inevitable that at some point, you find yourself (for whatever reason) in the drive-thru lane of a Burger King...even if that means you aren't the one driving.
In that case, all the author wants you to do is get a Grilled Chicken Sandwich and switch the fries for a salad with low-calorie Italian dressing. Get a diet soda, unsweetened tea, or water for your drink.
These decisions make all the difference in the world.
