The woman had an overflowing cart totalling over $500. Apparently, she, someone in her household or someone who had access to both her Costco card and her checkbook wrote a bad check for $700 a couple of days ago to Costco.
The supervisor was quite polite and informed the woman that she was responsible for that bad debt and that she could not shop at Costco until the debt was cleared.
What I found interesting was the woman's reaction. She was very calm and kept saying that she hadn't written the check and that she hadn't loaned her Costco card or checkbook to anyone. Then she claimed that it wasn't her check. When the Costco supervisor showed her the photocopy of the check with the woman's information, she then tried to say she hadn't loaned or given the checkbook to anyone.
I don't buy the woman's story. If someone else used her check, her reaction would be different. I know I'd freak out, worrying about identity theft and would be on the phone immediately with my bank. I wouldn't be trying to talk Costco into letting me write one more check. I'd be taking action to figure out what happened, cancelling my account etc.
Bad checks. It happens to everyone, sometimes you miscalculate and bounce a check. Just fess up and clear it and then continue shopping.
