I had an absolute blinder about 2 months ago. (It's also a very outing story because I shared it widely, so please if you recognise the story or me, don't out my user name!)
I had a yearling with a friend in Nottingham who was working with it, I live in the Vale of Glamorgan and before I went to collect it from my friend, I put the yearling up for sale.
The yearling was quite a desirable prospect, I had enquiries very quickly and so I had to explain to interested parties where it was and why and also when I'd be picking it up with the other horse I had in the same place...
One CF (who initially sounded sensible when I spoke to her) wanted to come and see it. Not a problem.
Then because she couldn't sort out child care, she came up with what she thought was the perfect plan. She wanted me to take it to her house on my way home, so she could see it to decide if she was interested in buying it. She lived in West Sussex.
The route from Nottingham to where I live in Wales is M1, M42, M5, M50, M4. I pointed out that "West Sussex" in nowhere near that route (not that I'd have gone there anyway).
She mentioned it was "a bit of a detour",and that I could stable my horses at hers overnight, she'd pay for a B&B and I could break up my journey a bit. The demands and requests became more ridiculous, including such gems as "You said price negotiable to the right home, I can only afford 50% of the asking price, you'll have to accept it as that's all I can afford and I want the horse".
In the end, I actually had to block her number, although I've kept all the texts and messages for amusement value when I want a good story to tell.
Then there was the one who sent me a random text, didn't even say who she was and said
"I want to enquire on your filly, what's your lowest price, I can get it quickly if the price is good enough"
Some buyers are idiots.
