I always touch and smell the fruit before I buy it -- don't others? Even if it's pre-packaged you can still eyeball it closely, give it a poke, etc. For soft fruits, I more often find them too hard -- but that's better than on the verge of rotting. Also, you can buy single peaches at Morrisons. Worst case scenario, I buy them on the harder side & let them ripen on the counter. But generally if I don't like what I'm seeing & picking up, I just don't buy that kind of fruit & move onto something else.
We buy fruit at the green grocer, at farmers markets, at the city market, and at supermarkets -- but no matter where I buy them, I always carefully check out what I'm buying before I buy it. I'm pretty good at it too - DH, not so much.
