Size \Small"Foot!!!!!"""

I went to Woolies @ Sunnypark Mall to buy some brandnew boxers, Im a size small so i bought small, cant fit underwear in the Store so i fitted them @ home, to my surprise, the so labelled size small happens to be big on me, even bigger than my small size boxers from other retailers say Markham, it was a pack of three n i had fitted one, so i go back to the Store with the whole pack, explained my situation to the CC Lady Who then called the supervisor , i told the guy id like to return that \small"size and rather take Xsmall"
