I worked as a sales associate. One day I was feeling sick. I ended up leaving early, but when I counted my cash drawer I was missing a check. I found out the next day, after returning to work, that I had given the check back to the customer. This customer came back to the post office later that same day I went home and bought more stamps. I had to pay for the amount of the check. Lucky for me the check was for only about $35.00.
