Life's Little Annoyances

There's a sign that's been hanging in my workplace kitchenette for a couple of weeks, and every time I go in there, I wish I had a pen with me.

Apparently, I am not the only one.

So, Please! (as the sign says) If you are going to make a sign, please (!) spring for that little extra punctuation mark!

Thank you.

(Nope - wasn't me.  I don't have one of those fancy phones with a camera in it.  I do, however, admire how the black comma offsets the bold red font so attractively).
