Paying for Convenience

I don't think some people grasp the concept of paying for convenience. I read recently that someone was "upset" that their $8 food delivery order ended up being $15 when fees and tip were added. To my way of thinking, that's just the cost of convenience. By paying $15 they're paying for the convenience of being able to stay at home or at work doing whatever it is that they're doing and not having to go out in presentable clothing, go out in who knows what kind of weather, go out and wait in line, and drive all the way back to home or work. All of that convenience is worth the $15 on an $8 order. The company facilitating your delivery deserves to make a profit. The person making that delivery deserves to make a decent wage for doing so as well. A $2-$3 delivery fee is just not going to cut it. If you don't think the convenience is worth the extra $7 then go out and get your own damn food.
