<human>: Can you provide a brief rundown of the text in within 3 sentences?

i work at a gas station, and this guy came in about 10 minutes because i shut down the main doors for cleaning. he goes into the back of the store and comes back with a pack of condoms. he buys them, and i think he's going to leave. he goes to the bathroom instead. few minutes later, comes out, leaves and i close up and start cleaning. i head to the bathroom to start and there...on the sink...was a used condom. some dude walked into a gas station, decided he needed to beat the meat into some plastic, and proceeded to do so. safe to say, my night was not as spectacular as i hoped it to be.
<bot>: guy walks into gas station, buys pack of condoms, masterbates into one of them and leaves evidence in bathroom sink.
