"I did not mean to cause offence," Autharyx said, even though the other had indicated he did not need to be polite. It wasn't a matter of politeness for him, but a matter of respect. And even than it did not have that much to do with Tezy. It was a matter of personal pride to show respect to those he thought deserving. Even the humans that had traded with him in the past had gotten his respect, even though they were so much less than he was. The humans he'd met on his trip thus far had felt... more significant somehow, but Autharyx was certain that had more to do with his current form than the capabilities of humans. 

When Tezy offered him the use of his washroom, Autharyx gave a small nod before heading in the indicated direction. He hadn't looked forward to the inconveniences that a human body would bring him, but at least he wasn't unfamiliar with any of them. Even without having seen the inside of a human house before, nothing proves to be terribly complicated and he takes the opportunity to peek around a couple of corners. Sadly there are no poorly-hidden treasure piles in sight and Autharyx has to accept that the house is indeed as humble as the human had suggested.

Although... not fully a human. Now that he is in the man's house, his scent is present enough that he can discern the particulars of it without too much effort. Tezy may not be fae or dragon, but he can't be fully human either. If Autharyx had to hazard a guess, he would say that he was the product of some kind of interbreeding between species, but it wasn't like he was an expert. It was not inconceivable that there were many creatures he hadn't encountered yet. He hadn't ever ventured too far from his waters, and he knew the world had to be much larger than that. He walked back to the table quickly, not wanting to seem like he was snooping. 

"I'm sure any food will be fine," he said, happy for the invitation. He hadn't even properly introduced himself, nor had he exchanged a gift in return for the hospitality, but he was following Tezy's lead in this. He had no real experience with human customs, and even if he had they would likely be antiquated by now.
