I know a girl who has been running an online business where she decorates and paints things like shoes, necklaces, and any other assortment of trinkets with anything that a person might want on them. So if you wanted a pair of shoes with a unique design, she would go buy a regular pair of shoes that fits the layout for what you want, then design it as specified. So a customer wanted a pair of shoes with a design on them, she went and bought the pair for $45, after painting and drawing what he wanted on them, he took back what he said and wanted something else. By this time, she could not return them because she already used them to the point where they could not be returned obviously, so she's out $45. The question i'm wondering about, is if it's her fault for not putting safeguards in place in her business to account for times when a customer might change their mind after the first thing they wanted is done, and they can no longer change their minds because they're bound to take what they wanted the first time by a contract or something, or is it the customer's fault for taking advantage of her?
