If you're applying the 'G' gradually as in pulling into a steep turn, you can 'pull to the buffet' if your aeroplane is gentlemanly enough (like the Chippy) to afford you such a warning. In aeros, however, the 'G' is often pulled on quite sharply and it's dead easy to go straight through buffet (even if there is some) into departure.
Also, some aeroplanes (the Yak 52 comes to mind from my experience, though I've heard the Harvard and others do it too) will readily flick out of a manouvre with no warning if the aeroplane is even a bit out of balance when stall AoA is exceeded.
