To those who said I'm selfish for saying FML, I was just following the conventions of the site. Trust me, the situation was awkward for me, but I so feel so much more sorry for the lady who called. She was meaning to call who I assume to be family or a friend to ask for toilet paper, but instead called the grocery store. I stayed on the line for a short while, but since we're not allowed to take personal calls at work, I had to refer her to someone else. I can only hope that she found someone to keep her company.
