I usually watch the credit card swiper box (does it have a specific name? ) to see the total building up so I know which card to use, and noticed only two yarns went through, but she had bagged three. I brought this up to her. She sighed, printed out a tiny receipt that showed what had been scanned thus far. "There is one marked yarn, one marked super saver." "Oh I rang up this fifty cent item twice." She fixed it, and started really dropping our items hard into the bag carousel. I don't think she even announced the total. I had some scanning trouble for some reason, but she just stood there like a statue. I got my receipt and left. On the way out (after getting "Have a good night! Thanks for shopping with us!" from one the really sweet greeters), I told my husband "I think I shoulda just pocketed the two dollars, jeez."
What one gets for being helpful, I guess. It's sorta sad I can't get hours at my job to save my life (luckily we don't need the extra income too badly), but folks with this kind of attitude are employed just fine.
Probably a minor suck, but I felt like writing it up. =P
