These are guesses too. I won't go into google maps but guessing attendance, one might wonder why they only have one service on Sunday. Many have two say.
@Cyber Liberty mentioned one purpose for having multiple services. Another, possibly more common, is that the number of attendees exceeds the capacity of the room in which services are held. E.G., the church of which I am currently a member has four services, two Saturday evening, and two Sunday morning. Two, and possibly three, of those services are typically pretty full.
I inferred from the church having one Sunday service (and none on Saturday) that its sanctuary is large enough to accommodate all attendees.
