As a single guy without a non punting phone I honestly dont really think about this too much, but I can see what you mean about the time frame. It does seem a bit too wide.
What I think is kinda strange is the fact the girl replied to you by text when you made a phone call. I think that if a client texts a lady he probably expects a text in response(assuming the lady accepts texts). If a phone call is made I would be quite happy with the girl just ringing once so I could call her back. If appointment was attempted by pm, then that is how I would be expecting the response.
Thats usually the way things have happened with me in the past and I never got any unexpected shocks from it.
I think in general us clients make contact in the manner we expect it to be returned. I stand to be corrected on this though .
