Rodney follows, ignoring the people in line, everyone behind the counter, and anyone curious enough to be following their progress from where they're seated. He's fighting impatience, so that when they finally get to the table, he thumps down into his chair with obvious relief and plants the coffee he'd brought square in front of Ianto.

"There," he says in satisfaction. "That's yours."

Waving away Ianto's question with a, "Yes, yes, everything's fine," he takes a moment to gather himself. Then lifting his chin as if that would give him any more authority, says, "It has come to my attention that you are sleeping with John and I still know next to nothing about you."

Which, granted, isn't fine, but nothing's on fire.
