Not the best customer service

I was at Target the other day to purchase a pregnancy test and a few other things. I get to the check out I put my stuff up on the belt and wait for the lady in front of me to finish her transaction. My stuff is now at the cashier, she picks up the pregnancy test, looks at me and says UH OH! She says this with the lady in front of me still standing there and now a lady behind me. I give her this look and then she ask "or is this a good thing?". I just could not believe she did that.
