Trog silently nods to the two Trolls at the bar, returning the respect they seem to be showing him. His attention then turns to the two humans, scanning them for possible weapons. The backpack makes Trog slightly suspicious, but they hadn't given the staff a reason to be hostile, so he simply kept moving his attention between the cleaner, the Ork, and the three at the bar.
He then sent a message to Concrete, Looks like you might be right Omae. Two Trolls as security guards, so maybe, just maybe, this place isn't racist. If we need you, there's two Trolls as security, a Human cleaner, another Human, and the owner is an Ork, just so you aren't coming in blind. Trog then continued to scan those in the room.
