It's my treat: I am treating you to this / the treat is from me to you.

2. yes, salesman. Who do we buy the break-room supplies from?
break-room, as I've explained previously, the room put aside for the staff to take their breaks (timed pause in work to relax) in.
break-room supplies - it sounds as if the company sells chocolate, drinks, etc. in the break room (sells the snacks to the workers).
