Hoping she just didn't hear you the first two times, you start to repeat yourself, yet again:
"Do you believe in love at first sight , or—"
She interrupts you at mid-sentence: "I thought that was what you said. You realize that's the worst pick-up line I've heard since my divorce?"
"You must not have heard too many pick-up lines recently, then," you reply, and flash your dentures, careful not to let them show in full. Damn that hockey puck in the mouth 10 years ago... but at least your teeth are straight now. Even if they're fake.
The redhead looks you up and down, smiling knowingly. "Would you mind getting me a drink from the bar, sweetie?"
This might be a scam — she probably just wants to use me for a free drink, you think to yourself. Aw, what the hell, I have nothing to lose.
You head back to the bar, weaving a little. The bartender glances at you, probably about ready to cut you off now. "Last call, buddy," he utters, while pouring out a beer. "Whaddya want?"
