Ok, so i know this cashier at this store i go to all the time. She asks me what I'm always coming here for with a big smile. i joked that I have a bed by the store's bathroom and I sleep in the store. She tells me to show her, we walk in the back and I tell her its gone in a playful manner. She laughs and that's when I knew she wants the D. She's called for customer service and I left without saying goodbye.

How do I escalate, How do I go in for the kill without fucking it up?
