See to something
Speak as Rachel
Speak as Wendy
Wendy: So, what do you need me to do?
Rachel: First, can you see to the seating arrangements. Make sure that everyone has a seat and that everyone is seated in the proper place.
Wendy: I can do that. Anything else?
Rachel: Yes, there is one more thing. After you finish with the seating arrangements, can you call and confirm that everyone on our guest list will be attending?
Wendy: Sure. I'll make the calls after lunch, and I will see to the seating arrangements now.
Rachel: Perfect. Let me know if you have any questions.
