Without much fanfare the people from the shop flooded out, many all too happy to oblige having desired a way to get out of that mess in the first place. But most importantly the two vigilantes were out of the way, and with them any twitchy reactions they could produce as well. The changer addressed Devon with agitation and a certain hostility. It's voice was, pretty much what you'd expect a creature of that kind of stature and mouth to sound like when it was trying to speak like a human, perhaps a bit more tired than expected. Apparently those vigilantes had soured the situation quite well before his arrival. Which was something he'd remember to thank them for if he ever saw them again. The creature however was more interested in food than in him, and given that it had stated that it needed food and was pretty efficiently dining away what was perhaps a months worth of food, it seemed pretty likely he really needed food.
The situation sharpened further as the changer turned his attention from the food to Devon, apparently and not entirely ungrounded seeing him as a major threat. The creature spoke once more this time in a higher and more painful voice as it reacted to seeing his assault rifle. Devon cracked a small smile as it basically asked his assumption of the rifle being loaded was correct. "Actually, it's empty. Like I said, I'm just here to talk and I can't exactly just drop a weapon randomly on the street. But how about you eat first, and we talk later. If you need more food, I know a place or two without the mass panic... Or the need to jump a counter, my treat." He said slowly motioning his free hand to the magazine pulling it out and giving the creature a full view of it's empty insides. He then re-inserted the magazine into the weapon.
However as he explained his intentions the changer had taken on a form he could only describe as aggressive, this thing now literally looked armed to the teeth. A rather impressive creature were it not for the fact that it might be attacking Devon. It came out from behind the counter, seemingly being more mournful about wasting food than anything else. Making an educated guess Devon assumed that him needing food was tied to his shapeshifting abilities, likely with him needing food to grow. At any rate that was less important than the immediate danger of having a fight with that beast right here and now. The entire situation favored the changer, there was only a short distance, confined and cluttered space, even if he'd kill the thing before the first charge hit the momentum of the corpse would still hit with a dangerous amount of force.
Devon sighed putting his free hand on the table he was leaning against. Both as leverage in case he'd have to dodge and because it was more comfortable than leaning on the edge with it's full weight, it was pushing his armored vest into a rather uncomfortable position. "A couple hundred dollars worth of food, easily resupplied by tomorrow afternoon, or a couple thousands dollars of damages and a business with closed doors for weeks cleaning up the mess. It's a simple equation and from what you showed before I entered you seem to not want to fight without reason. And like you said nobody is hurt, so I don't see any real reason to fight you. I'd rather not be known as the hero who trashed a sandwich shop, or even worse got trashed in a sandwich shop, over a couple of footlongs. He then said as a final plea to sensibility, in the hopes to avoid having to fight the changer in this confined space. The place would get absolutely trashed, probably both would be hurt and he probably won't even have the option of holding back on the lethal firepower.
