It wasn't that Hashirama disliked his job, far from it, he adored all his fans and loved interacting with them. It's that sometimes he just wanted to feel like a normal person like everyone else.

That's why he sneaks away every Friday evening to visit the convention store at the edge of town. He was honestly surprised that the cashier didn't know him when he first visited but now, he was thankful they didn't because it meant he could talk normally with the cute cashier he may have a crush on.
