So, this girl and her Boyfriend came in a couple of weeks ago to buy a guitar amp from me. Seemed like a cool couple. They ended up finding one that they liked for about $500. Well, the check they paid for it with was made of rubber and it bounced (like rubber checks tend to do) and what does she do? She comes in TOTALLY pissed off at me because, as she put it, "When I wrote you that check, I had the money in the account, but you deposited it a day late and the money wasn't there! Now my boyfriend is going to kill me!" I couldn't tell if she was joking or not! I explained to her that it's not my responsibility to manage her finances, but I would be cool with them and let them pay me back in a week with no additional charges, which I thought was a pretty nice thing for me to do. However, she then continued to tell me how it's not very responsible of me as a business owner to not deposit checks the same day I get them and that it's STILL somehow my fault that her check bounced! I deposited the dang thing the day after she wrote it! I'm dumbfounded. What kind of logic is she using to turn this into my problem?
