Does each servant requirement need its own servant, or can one servant do double duty?

Question

Accepted Answer

Each requirement needs its own servant: a tile and each guest that shows a servant icon each take one from Available Service, and two valet icons need two valets (unless an effect substitutes). A servant can never do double duty, so one Housekeeper cannot cover both a tile and a guest.
