People in general don't like there time wasted and if you had mad a descision then yes you could say "Sorry but I'm going to agree we would not be a good fit and lets finish up early as I have taken enough of your time". The smart thing is to remember interviews work both ways and if you have concerns then ask them directly in a way that its a show breaker and put the onus upon them. There might be a situation were you dont like something and by telling them then they may very well change it and as such your saving alot of time and potentual mistake. They may very well say it wont happen or give a vauge promise and from that you also know were you stand with clarity and are also in a better position to say sorry for taking up your time and end there. Both can end on a good note, the later is the smarter play though.
