Riptide will try to stand still, silently noting there's nothing here he recognizes as food. The conversation is well above his pay grade, though he's pretty sure if he was in charge of the negotiations, they'd be done already. He can't help but yawn loudly, but if it attracts attention, he will scoff at the guard beside and mouth the word "rude" in the guatd's direction if anyone looks.
This makes a little more attentive, and he starys to eye up everyone who's not on the team, checking for any physical foibles... fumbling for utensils, awkward or inefficient habits, signs of nerves, anything that would make them seem out of place.

It's been a long time since I rolled anything, so I'm guessing what die to roll🙁
