Do you need Plan B??

I was so confused when I went to Walgreens and asked an employee where her pregnancy tests were and she gave me the ugliest look I have ever gotten. She walked me through the store almost muttering to herself and thrust her hand towards what I thought were the tests. I asked if this was all she had because I didn't recognize the brand and she spit 'well we have the more expensive Plan B.' I didn't even know what to say other than that's not what I asked for. when she realized her mistake she glowed and took me to the tests which were on the other side of the store. Although I wasn't there for Plan B I know a lot of women make that choice as a backup form of protection and I don't think she should have acted that way. What do you think? EDIT: I HAD TO ADD A PICTURE OF THEM WITH THE PERFUME SINCE PEOPLE DIDN'T BELIEVE ME!!!
