Could you please help me?
1. What's the word for someone who works in a company and they need to provide supplies like food, and necessary things for a company. Also, we have these people in cinema industry. Is the word the same for both of them or different?
2. What's the word for someone who makes tea or coffee in a company and cleans a company(such as sweeping, mopping the floor etc)? Is it "janitor, caretaker"?
