I have recently started to grow some plants and we had been discussing putting any surplus out for neighbours to help themselves or something similar.
I used to love it when driving through the countryside or small villages and seeing small stalls set out with fruit, vegetables/salad, eggs, honey, preserves etc - some of the things in jars even had pretty homemade labels and list of ingredients (good for people like me with food allergies). I love the concept of honesty boxes and personally would always rather leave a little extra than see it as an opportunity to get fresh/organic homemade produce free or cheap! I did used to be amazed when other cars would pull up and someone would get out, help themselves to items and get back in the car having put nothing in the box. I recall a few, usually smaller, farms or orchards had a 'pick your own and leave something in the honesty box' opportunity - doesn't get any fresher than straight off the tree/bramble etc - even windfall apples, pears either to collect yourself or in baskets or boxes on the stalls. A little bookshop in Hastings used to leave about a dozen boxes of books outside and a note saying to put the money for priced boxes or a donation for books in other boxes through the letterbox - again, bargain books - I do remember posting the money and seeing other money all over the floor - used to wonder why no box or tray to collect the cash as they would have to pick it all up!
I do agree with previous comments though that these days there does seem to be a greater number of people out to get things free, that have no respect for things like honesty boxes, even if the money goes to charity or being able to provide more goods for people who need them.
I may have to think further about what to do with any excess produce I manage to grow - maybe the food bank would be a better option! I did also think about putting boxes of books with an honesty box to raise a few quid for our local animal rescue, but seeing others have had problem neighbours threatening to report them for selling etc I don't want to upset my new neighbours in any way - sad world when you can't even try to do something nice without being condemned, short-changed or robbed.
* Just in the hope some of you might see the funny side of this....most of us are of an age where we know 'Pick Your Own' means collect your fruit then pay for it....my better half told me of a time he was out with mutual friends, went to a PYO place and on the way out one friend thought he would be paid for collecting the fruit rather than having to pay for what he collected - we couldn't believe it as he is about a decade older than me - did think it was funny though, even funnier that he was then told to cough up and pay by the others present and he is notoriously stingy.
