habitual offenders

There's these two women who pull the same routine every time. One buys stuff than constantly tries to return it without a receipt. It always winds up turning into an ordeal. Today, she came in and has done so many non receipt returns, she couldn't do it. Guess who had to break the news to her? The trainee that was up there. Then there's the other one that always buys clearance stuff. So when she returns it, someone has to match up all the new clearance tags or has to defect the stuff out. When one is doing the job of three people already, this the last thing they need.
