In fairness, anal is always at discretion and at least she told you in advance, rather than saying yes, taking the booking and your money - then saying no. That would definitely be worth a negative.
It may be that she does anal but her arse was sore after recently doing it with another punter, hence "not today" but it's hard to know for sure.
FK and/or OWO are standard services and if a girl promises to do them on her profile but doesn't, then that is worth pointing out to other punters - on the region's general discussion board if no meeting takes place, review board if it does.
