<prompt> Human: Hes asking for the check back now that he has back out of the sale, but Ive told him since hes committed to buying, Ive taken down the ad and denied multiple sales requests. Is it okay for me to keep the 100 check hes given me? or am I legally obligated to give it back?Edit: I turned 4 potential sales away and took the ad down. The only reason he changed his mind is because he originally thought it would tow his boat but now he thinks it will not.Assistant: Did you agree about paying him back when first made the agreement? In most cases, you would keep that money, as you stated you had to deny other potential buyers, and remove your ads. Ive heard it referred to several times as the holding fee, incase you need to put back ads back up. he sounds like he will just cancel the check no matter what.Human: I did not agree but nothing much was said other than, Ill give you this check to hold it for me.  <response>: Thats all you need to cash it.
