is it too much?

“Hi! Could you work on Sunday night?” my boss asked to the new sushi chief who just got his job here. “Oh. No! I have to go to church on Sunday.” He answered. And then, my boss was looking at me for 2 minutes, I knew his means, and I have same thought as his. I continued to ask him, “Why?” “God needs me on Sunday!” he said. “God needs me too! But he wants me to work and contribute to the society, and he said your work place needs you!” I said.
You may feel unusual, but it happens. I respect to every religion, but it is too much! I don’t know why people believe god, and they must go to church every Sunday. It is two completely different events. Now, a lot of people go to church every week, but I think some church just guide people to a wrong way or they want to tie more and more people in their church. It is not a business because it is pure religion. I don’t know what happened to my work partner, but I seriously think something wrong.
“If everybody goes to church every Sunday, every store and restaurant should close right?” I said to my cow worker. “Yes!” he said. My boss and I laughed.
