Super (exciting) Market

I have this fantasy where 2 random people get accidentally locked up together in a supermarket. Because they can't contact the outside world they decide to have some fun and eat/drink from the store supplies and go trough the store isle by isle. They get to know each other well and talk about their lives. But everything changes when they arrive at the isle where the condoms and lube and sex toys are sold.... In the morning they leave the store and leave all their garbage behind (used condoms included) and manage to sneak out.
