Scent specifically says "A creature with the scent ability can detect opponents by sense of smell, generally within 30 feet. If the opponent is upwind, the range is 60 feet. If it is downwind, the range is 15 feet."
Lets consider real life for a second! Firstly a real life comparison...
using my natural 'sight' ability, I can 'visually' detect opponents within a far greater range than 30ft, on a nice bright day in the open I can detect even further using my natural 'sight' ability. Sadly however, this does not make me immune to ambush or as is more likely, someone sneaking up and shouting boo! Even with my might 'sight' and 'hearing' ability this is still possible. So the big question is, why would this be any different for 'scent'?? My cat has a much better 'scent' and 'hearing' ability than I do, and given the right situation, I can sneak up on her!
Secondly lets apply a little logic...
Scent, an ability given to almost all 'animals' in the game! Should it really be that powerful as to make you immune to ambush? I really think not. Besides, there would be a lot of 'ambush' hunting predators going hungry if that was the case, since most of the pray has the scent ability.
I would suggest you tell your player to get a grip and stop being a mook!
