Read the Signs

Something at work has been bothering me since I started at the end of January. It's a sign on the inside door of a stall that reads:

PLEASE MAKE SURE TO FLUSH THE TOILET COMPLETLY. HOLD THE HANDLE DOWN FOR A FEW SECONDS OR IT WILL NOT FLUSH.

It irks because a) the universally capitalized command makes me feel rather like a child who is being yelled at and b) because their spelling of the word "completely" seems . . . er, less than complete.

Lynne Truss would be proud.
