wifi access on sites

I would appreciate other members' views on the wifi now available on site.  Due to family problems I took my lap top with me this weekend and paid my £5 for 5 hours.  This is paid to an outside provider and I think in the days of free wifi all over the place now, it is not good value for money and goes very much against the so called 'value added' ethos of the caravan club.  I suspect that the club (our club) has paid over the odds and locked itself in.  But what is really annoying is that having used 1.25 hours, I closed, closed, closed down my laptop and went off to enjoy myself.  5  hours later I returned and went to check my email only to find my time was up - apparently I had not logged off.  This is archaic.  The website said speak to the staff which I did and they said nothing to do with them, not logging off uses all your allowance.  They gave me the number to phone to see if I could argue back my allowance,  Caravan Club, I am on holiday I DO NOT WANT TO SPEND ANY TIME ARGUING OVER THE PHONE WITH A GREEDY PROVIDER OF WIFI, FREELY AVAILABLE ELSEWHERE.  Why on earth have you arranged this ? Can I please have some feedback to let me know if it is me being unreasonable.
