I just looked at a showcase that quoted rates for 30 minutes, 45 minutes, one hour, 90 minutes, and two hours (actually, "120 minutes" was quoted, but, you know). Most of the time, when both a one-hour rate and a two-hour rate are quoted, the two-hour is somewhat less than twice the one-hour, which makes some sense: some "overhead" (preparation and screening time) are already covered. But in the showcase I just saw, 60 minutes was $250 and 120 minutes was $550. That's unusual -- being penalized monetarily for wanting a longer appointment -- but this wasn't the first time I've seen it.
So, what's up? As I see it, two possibilities. One, the lady really doesn't like spending two hours with one client, and sets her rates to discourage that. Or, two: maybe she's having an arithmetic issue?
Part of me wonders what she'd say if I asked to book one hour, followed immediately by one hour. I won't be finding out, since I won't be in Austin anytime soon, besides which she's a smoker. But I am curious.
