THE 'I DON'T GET IT BECAUSE I'M FROM FRANCE' LADY

this lady comes up to the register and wants to exchange some vitamins she claims are expired for some new ones. so, the first thing i check is their expiration date, and lo and behold, they expire in may of '06. she claims they say they expire may 6, of this year and i try to tell her that they are not yet expired and that it means may of 2006, but she tells me that she is going out of the country (to france) and wants some that have a longer date. so, the next thing i check is to see if they are the same product, since, if they are, we can do an even exchange and not have to fill out all the paperwork. of course they are some different vitamins. however, they are the same sale price of $5. so, i have her fill out the paperwork and do the return for her, keeping the cash in the drawer. now, since she had some other stuff she was buying, instead of ringing her vitamins up separately, i rang up everything together and subtracted the cost of the vitamins from the return, which was like $10.78. well the total without the vitamins was like $27.XX something. the original price was $37.XX minus the $10.78 for the vitamins. when i told her the total, she got all flustered and was like, "but i was supposed to get the vitamins for the same price!" and i was like, yes, you did. i even showed her the returns receipt where she was getting back her $10.78 and she still didn't get it. unfortunately for briana, she was standing nearby, so i had her come try to explain it to the lady. she even tore off receipt to show her where i had subtracted the $10.78 from the total and the lady still didn't get it. she didn't realize that the other stuff she was buying added up to $27.XX and for some reason didn't want to pay for it. so here we were, trying to explain to a french lady that wasn't understanding what we were saying, that she had to pay for the added items, even though she was getting the vitamins as pretty much of an even exchange. she finally told us that she didn't understand and that she was just going to take her vitamins, leaving us with a bag full of products and an overring. she got us both frustrated on that one...
