My Entitled Roommate Tipped Me $10 For A Month Of Meals, So I Ruined Her

After picking up meals for my roommate for an entire month, she handed me a crisp ten-dollar bill.

"Babe, aren't you on a diet? Keep doing it next month. Walking back and forth to the dining hall is great cardio."

"Technically, since I saved you gym membership fees, you should be paying me. But I'm generous, so keep the ten bucks as a tip."

I stared at her in disbelief, furious. "I fronted over a thousand dollars for your food this month! You give me ten bucks, and I'm supposed to thank you?"

"Wouldn't you have to pay for the gym anyway?" She rolled her eyes.
