"Your concern is noted." It's said in the driest tone of voice he can manage. And without taking his eyes away, the bar returns to its usual hustle and bustle (with one very confused gentleman wondering how he managed to drop his drink). He wouldn't want anyone to think he has his guard down, after all.

But, after an extra beat or two, he does turn away to look at Erik. He knows that it's not anger the other man is feeling, can sense the upset and frustration, but he doesn't say anything. Instead he meets Erik's scowl with a fierce look of his own, eyes flicking to the exit and back. Let's leave, please?

He turns half-way to give a polite (if stiff), "Good day, Logan," before setting off. There's no need to forget manners, after all, even if they'll most likely be met with scorn.
