I almost wanted to buy an item on eBay, but the item in the photo was placed on a bed with the bed sheet not only all wrinkled up, but there seemed to be some stain on it.
So I was considering another seller's item, but I send to that seller:
friendly reminder: maybe you can place the item in clean and tidy background so the buyers won't need to worry about it
I really wrote this message out of kindness.
But two days later, I got back a message:
You really have all the time to go around in the world and complain about things. What a clown.
Do people really think what they do are always right? What could I have done?
