For the most part, David hadn't been paying attention. Two drunk girls in a bar. It wasn't something new. Especially not these two. He'd gone to school with Noelle, and was a year older than Cait. So he knew she was under age, but didn't really care. Noelle tipped well. Especially when she was drunk. He wasn't really sure what her and Evan's deal was, nor did he care.
He looked up from making Noelle's drink, however, when he realized Cait was addressing him this time, instead of just talking about him right in front of him. He was used to it. These two came in all the time. Noelle would get drunk, Cait would get tipsy, (which by the way always amazed him, as she usually drank quite a bit more than her sister and only got a little buzzed from what he could tell. For him, it was a bit of a turn on when a girl could handle her liquor) and they'd talk and giggle, sometimes about him, sometimes about other people.
"You're asking me to have sex with your sister?" He asked with a raised eyebrow as he set Noelle's drink in front of her and mopped up the counter where she'd spit margarita-ice-water all over it after Cait's spiel. "Where do you factor in? Do you plan on watching? Video taping?"
