I have done a lot of renter check outs over the years. Some of the least fun have been with new CPL's from College programs ( the Canadian equivalent of UK integrated programs) who have drunk the school cool aid and think they know everything because they are a product of the XXXXXX school program. I remember one young sky god that was horrified that he was actually required to fuel the aircraft himself and just could not just tell the dispatcher what fuel load he required
My experience is the length (and therefore the cost) of the checkout was directly related to the amount of preparation the person put in. Those that made an effort to learn the club procedures, review the airspace, had a good handle on the POH and kept their ears open and their mouth shut usually had a pretty quick check. I, however had no problem putting the boots to those who kept on saying "but that's not the way we did it at XXXX"
