Went to a 2nd hand baby/toddler event today, one where the sellers are parents selling on their unwanted to stuff. Bought a couple of bits for DD that looked ok at first glance, when I got home found a puzzle had dried on food on it and a plastic supermarket trolley with thick dust on the underneath. I also picked up a couple of things in there that as soon as I had them in my hand could see they were grotty. Is it too much to expect people to give their things a wipe down before asking money for them?
