What's Wrong with this Picture....

These two fine Irish workmen toiled throughout the day installing bollards to stop Nurses parking on the pavement outside the Royal Hospital in Belfast, Ireland.

The photo shows them cleaning up at the end of the day...

How long do you think it took them realise their mistake? Apparently this photo is the original and is undoctored (?!) so to speak. Dear oh dear... 

Think Long and Prosper
