The Blessings of Product Variety

A SoCal phenomenon I don't understand is In n' Out Burger. People around here rave about their burgers; to me they are not worth the calories and fat.

Don't get me wrong--I like lots of food that is bad for me. Tommyburger sends me to the moon. But while others find consumption of In N' Out puts them on indifference curves that are tangent to their budget constraints, it leaves me on an indifference curve that cuts the budget constraint.
