Hope for humanity

Yesterday Zabeth and I went to town for some chores. One thing on our list was to put minutes on the cell phone. Immediately we found a megastore that dealt all major brands and other sound equipment. The lady at the counter showed us what we needed to do and how much time we could add for 25 dollars. Then she walked us to the register to pay, I forked over my card and was only charged 15. I didn't say anything until we left,nut Zabeth noticed too that the price was low. I was concerned that we had just been had,nthey take payment but nothing happens on our phone account. Worse yet I gave them my credit card so they could feasibly charge more after we left.nthe next hour I was moderately consumed by the notion. Then we received a text saying thanks for purchasing credit, so we felt relief. Then ten minutes later the lady who waited on us called and said that she undercharged us, it seemed she lost the figure in the translation. Went from being vulnerable in a foreign country, to being responsible for this nice lady losing her company ten dollars. She asked us to come back? Seeing as how we went from the had to the haver,mew could have easily avoided the situation forever, but understanding the angst we felt all morning until she called, we dutifully walked back to the store and gave her the rest of her money.
