So I went to wal-mart yesterday to pick up some things. Anytime I go there (which is not super often) I stock up on the 88cents hpt. So I grabbed 5, which I actually thought was using self control because I really could've cleaned them out! Lol. So anyway, I go to check out. I was wearing my scrubs, I work in the medical field, and the girl says "oh are you buying these for work?" I politely smile and say no. She said"well I can tell you they're really accurate. I wanted to say ummm no bitch I take like a million of those things!! Made me laugh. So the you-scan it is for the future;)
