Ooh I've just remembered one. When my second was 6m, I sold her vibrating bouncer for £10 on marketplace.
Woman makes contact, almost immediately asks if I deliver. I say that I'd rather not as we've got a 6mo and an insomniac 2 year old, but I could ask my husband if he could. Ask where she lives?
She says X road, and she needs it delivering as she doesn't drive. I inform her that I'm also in X road. She tells me precisely where, and I tell her where I am - all of 200m away (I can literally SEE HER HOUSE her house). Her response
'can you not deliver then, Timmy (name changed) had got a cold, can't bring him out'.
why I haven't told her to get lost I don't know, but I meekly agreed to deliver. But not right away as toddler is napping and baby is asleep on my boob. So she sends her husband round to get it straight away (because even he likes strangers walking in their house when breastfeeding...)
Thank goodness that was over, what a pair of CF's, I think.
Half an hour later, she complains that it doesn't vibrate properly. She can return it for her money back if she wants. She decides to keep it. That evening she changes her mind again and asks to return it.
I give her the tenner back, put it back on marketplace and sell it to someone else advising it may need new batteries. It works for them fine, no complaints.
Seriously, who demands (there was never even a please or thank you) a handheld item be delivered 200m?
Urgh.
