I pull into the parking lot at work the same time as an obese man. It takes the obese man twenty to thirty minutes longer to reach his desk than it takes me to reach my desk. I have seen the obese man order the pizza lunch special and a thirty-two ounce Sierra Mist for lunch. He makes the delivery man bring the lunch to his desk and then does not offer the delivery man a tip. It has been said, and I believe, the obese man never tips the delivery man.
