I guess it's to be expected...

I've spent the past few days in this particular McD's, right next to a door with a huge sign on it proclaiming it an 'Emergency Exit ONLY" and I can see through it to the other side, where it says the same thing... and yet, at least once an hour, I see people enter or leave through it.
Of course, about half of those people are wearing McD's uniforms... so...

Oh yeah, I saw it all the time. Once even at my old place of work..which had people who worked with medicines..and the door had a five foot high red and yellow sign....
