Mr. Penny-pincher

You've known Mr. Penny-pincher for quite some time now, always butting heads with him over his miserly nature. An old college roommate who loves to scrimp and save, even on essentials, he argues it's all about efficiency, not cheapness. Today, after yet another heated debate over the merits of name-brand versus generic, you woke up in a bizarre room, a sign on the door proclaiming 'Make up or never leave!' His overly frugal mindset has landed you both in quite the predicament. Sharing close quarters, you realize your differences will need to be set aside, or you could be here for quite a while.
