Blonde Moment

So I am in the check-out line at Target today. My girl checking me out had a speech impediment and I am trying hard to understand what in the crap she is saying as we carry on a conversation. I take my debit card out of the machine and start loading my cart with the groceries. The girl tells me that she thinks my necklace is cute. Then she hands me my receipt and says, "and cute bum too." As I turn around and give her a really weird look I am thinking "she is literally checking me out" and then she repeats..."and coupon too."
