While everyone watched as the other players were rounded up by the NPC guards, the cause of all this as well as the centre of attention, Sato, had already finished up with the attendant and sneaked out of the trade-house.
All Sato needed to do was to sell his weapons to the trade-house and leave but as he wanted to avoid the attention of so many players on him, he just handed the weapons to the clerk and said he will come for the money later. He wasn't worried about not getting it as first of all, these were NPCs and though programmed like humans, they were still more trustworthy than humans. Also, he would still be doing a lot of businesses with the trade-house and so, be visiting the place over a long period. Hence, collecting his money now or later made no difference to Sato.
