Why so little water?

Why do restaurants provide under-sized cups when you ask for water with a meal?

Is the cost difference between this little clear plastic cup and the regular soda-pop cups so huge?

Are you trying to force me into ordering soda-pop by ensuring I can not quench my thirst with water?

Are you thinking I will be too lazy to get up and refill this cup as often as it would require and thus I will buy a larger soda-pop cup?

Have you never been thirsty for water in your life?
