Quick lil story

Guys this girl and guy came in today and like I'm helping them right, and I look at the girl, and

She's got a HUGE hickey on her neck, she was a lil white girl and the guy was like very cholo-esqe roght so I look at her one more time and she's like BUSTED. Like she looks like she just got

Fucked. Hard. And the guy gets up to the cashier to pay for food right and we say together or separate and he STRAIGHT UP says " idk, are hookups supposed to pay for each other? Like we just met" and MY JAW DROPPED. And the girl was like " no I can pay for myself... " like all quite like and I'm like BOY WTF YOU DONT ANNOUNCE IT . And the girl on cashier looked at me and I was in SHOCK.
