Ha! I was selling appliances a few weeks ago and I was astounded how many people asked me to hold things. I told them I only hold "Paid for items". You come and pay me cash, and I will hold it. I had to remind people, "I am not an appliance store."
Another guy wanted me to hold a freezer, then said he had no way to move it so he was going to have to hire someone and then asked me to lower the price by $100. so he could hire someone. I told him "Sorry, not my problem. You pay what I am asking and you figure out how to move it."
Can you imagine?
He had the gall to tell me "it was not fair that he would have to pay to get to his home". I told him, "this discussion is over. Go home and think about why it is NOT my responsibility to give you a discount to have this moved.
Usually I have no problems selling anything on craigslist, but with the appliances, it brought out all sorts of clueless people.
