Although if there's a cash register or mailbox nearby, the farmers would of course prefer to get paid.

Typical prices in grocery stores for apples seem to be around a dollar a pound, but apparently farmers get roughly a third of that: http://www.agmrc.org/commodities-products/fruits/apples/comm... I'm sure they wouldn't mind you cutting out the middleman if it meant a little extra for them. But so far all the apple picking operations I've found are tourist attractions, and charge even higher prices than a grocery store.

Unless you're leaving the field with 5kg of apples, I doubt they'll care. But, this is coming from someone who plant fruits to eat them. We're not selling anything to grocery stores.
