Help me think of a sales joke!

In a medical store, a dissatisfied customer said to the manager: "I don't want the moisturizing cream you sold me last week. Please return the money to me." "Why?" "You said it was used to fight hair loss, but it doesn't work." "You try it again. I said that this moisturizer can be used to fight hair loss, but I didn't say that it will definitely work. Victory."

A notice was posted on the door of a major American department store, which read, "If there is no stock, we will be fined US$100,000." A French tourist wanted to get this US$100,000. After walking around the company for a week, he went to find the manager of the company and asked, "Where can I buy a submarine?" The manager took him to the 18th floor. There was really a submarine in the toy stall. The Frenchman also said he wanted aliens, and the manager took him to the "Future World" stall. As expected, there were several alien models. The Frenchman refused to give up and asked: "Are there any women whose belly buttons are above their eyes?" The manager calmly said to a saleswoman next to him: "Come and stand on your head to show this customer."

In a handicraft store, a woman was questioning the manager: "The ivory box you sold me last week was fake. I asked someone to identify it. It was not made of ivory at all." "Excuse me, madam. Maybe that elephant once had a denture..."

A young woman was shopping for a hat: " I like this white rabbit fur hat very much. I wonder if rabbit fur is afraid of water?"

Salesperson: "Of course not. Have you ever seen a rabbit holding an umbrella?"
