Myself, another guy, and a girl had the following conversation.
Girl: I'd really like to try restaurant X.
Guy: I'll call and see if we can get in
Me: I hear it's really packed there - kind of tough to get reservations on short notice.
Guy: I'll see what we can do - I can usually schmooze my way past reservations people.
Girl: That'd be great if you could...
Guy: <goes off to make a phone call, comes back two minutes later.> No, they could only seat us at 10:30, next weekend.
Me: Let me try. <Calls my personal Centurion Concierge, comes back 2 minutes later> OK. We're set for 8:30, table for 3.
Girl: Really? Wow! You're really good!
Guy: Grumble.
That, right there, made it worth it.
OK, that doesn't make it ENTIRELY worth it, but it certainly helps.
