I have only sold at one , and yes experienced the same problems . One family seemed to operate on the principle of annoying you to the extent that you would just want them to leave . 6 brand new boxed expensive glasses - 50p ' No i give 5p ' , ' No there 50p thats a bargain ' .
'OK 10p ' etc etc
Agree on ridiculous price of 25p to get rid of her , while I'm sure others had pocketed a few things . At the point of handing money over she them pushes a load of random items in with the glasses in a pile and give me the same money . So i stopped that and she started again with something else with the same result .
I find it extremely rude when someone is trying to force you by annoyance to give them something for absolutely nothing , when you are practically giving it away anyway .
They annoy me almost as much as the people walking alongside your car when you get there then trying to get in your boot before you are out of the flippin car !
Best one i went to was Henley on Thames , i got a small oxy acetalyne set for £10!!
That's what we had too from a few people said a price got a stupid offer back, told them they were taking the Micky and Id rather chuck it with the scrap brass or alloy, I got told I was a hard man to deal with but they did come back and buy them for the price I said when they figured I wasn't joking....Facebook is easier for getting rid of tat to be honest
