Laughing, Derek shakes his head a little and wrinkles his nose. "I told you I'm bad at technology," he says. In his own defense, the laptop had been in a suitcase sort of case, but he refrains from sharing that at this point, because if he says so at this point, it'll just sound like an excuse.

Derek gets to his feet with a smile when she says she'll still be here when he gets back and he makes his way to the end of the line. Honestly, he's not that interested in a drink, but he's sort of hoping that if he does, then he can have a legitimate reason to prolong their stay.

It takes several minutes longer than Derek would have liked to get to the front of the line, order a black coffee with a double shot of espresso, and get back to the table, but at least it isn't long enough for Felicity to get bored and wander off in spite of her reassurance. He settles back into his chair and takes a sip of his coffee before smiling at her again. "So, is it bad if I say I'm still curious about what you were too worried to share that first time we ran into each other?" he asks, unable to help himself any longer.
