This means you.

There's a person at work who is forever talking on the cell phone while in the restroom. For a while I thought I was the only one maddened by this rude and inconsiderate behavior. But at the office Christmas party, I learned I wasn't the only one driven to insanity by this woman treating the ladies room as her own personal phone booth.

Shortly after the office Christmas party, the following sign was placed on the restroom door:

Please be courteous.
The public restroom is not the place for a cell phone conversation.
Thank you.

And for a couple of weeks, all was well. But yet again, the woman was spotted walking into the bathroom with her phone glued to her ear today. I can only assume she thought that sign was meant for someone else, surely not for her. So in order to make things absolutely clear, I'd really like to make the following edits to that sign (when no one is looking):

Please be courteous.
The public restroom is not the place for a cell phone conversation, Hacky McSmoker's Cough.*
Thank you.

*Offender's actual name will be substituted on the bathroom sign.
