We run an Ebay clothing business and get weird/awkward/demanding/cheeky buyers ALL the time.
Recent things include:
Someone who bought a pair of herringbone trousers, which were listed clearly in the title and listing as being herringbone AND photographed in a close up shot to show the pattern, started an Item Not As Described dispute because "The trousers have a pattern on them"
Someone messaging me asking if a pair of kids shoes I was selling would fit their child.
Someone starting an Item Not As Described dispute saying that a pair of shoes I sold to them didn't have a size stated in the listing. They did have a size stated, and a photo of the labels stating the size, but if it was the case why the fuck would someone buy a pair of shoes not knowing what the size was? And she started the dispute after messaging me saying that they were too small for her and she was surprised as they were a 5 and she was 'always a 5'.
Plus loads of people getting arsey when they can't fit into something, and trying to blame us, despite us putting sizes and measurements very clearly into each listing. Very rarely does anyone just politely say that the item doesn't fit them and could they return it; it's always done in an accusational way as if we've made their arse too big to fit into a pair of jeans or something.
And probably best I don't even get started on people who send a million questions about a £4.99 item before buying it, then ask if you'll accept £4.50! No! Just No!!
