Once the tournament was over and he collected all his winnings, Tetsuya did not forget to go collect his winnings from the bet. Although he did not get first which, even without his 'bad luck' he probably would not have gotten, the bets were on his being in the top three. Unlike Brent, who had multiple sources of income to support him, Tetsuya did not so every spirit coin mattered. Naturally, since he was stepping into the public, he was wearing a facemask to hide his identity. He wasn't oblivious to the fact that he wasn't well liked, but couldn't find it in himself to care. The only reason he even wore a mask was because his time was valuable and better spent elsewhere than arguing with an idiotic mob.
When he went up to the counter to collect his winnings, he did not bother with any small tack and just handed the man his slip. The man, on the other hand, could not prevent himself from chatting a little.
