I love the idea of freecycle, but loathe actually using it, purely due to so many ungrateful and selfish people who either just grab it and go without a simple thank you, or those people, like others have mentioned who ask me to ensure I keep it by until they get there, then I never hear from them again.
One woman wanted an almost brand new single bed which had another pull out bed underneath. She knocked on my door, said 'I'm collecting the bed', then not another word, whilst I helped her carry it to her van and get it in, then she just climbed in and drove off without a backward glance!! I always hope the things will go to someone who really needs the item and/or has decent manners.
One chap asked me to keep something and turn others away, until he could get to me at 4pm next day. He didn't turn up. When I messaged him, he just said 'I was asleep. I'll get it tomorrow'. I told him he wouldn't as he was so rude, and he gave me a torrent of abuse!
Another time someone wanted something, and when I said 'what time would you like to come' he answered 'You can bring it to me, I don't want to pay for petrol to get there'!!! Luckily, I don't drive so said I was unable to deliver (not that I would've anyway!), turned out he lived about 40 miles away!!!
