You know what? You're right. I did it. I went out to the parking lot with my groceries and took a screwdriver/ice pick/etc and punctured the soda cans. I decided that I wanted to get all of my groceries and my car drenched with diet Pepsi because, you know, it's a slow Monday.
Sorry I got your floor sticky. My humblest apologies.

Yep - she actually told me that she couldn't let me exchange the 12 pack because she didn't know when I bought them (even tho I was showing her the receipt printed out 3 minutes prior) and didn't know if I'd punctured the cans. o.O ? Luckily the cashier who'd checked me out helped me.
