You know... I'm just one of those kind of people that would have to tell them i messed it up!!! Besides.. if its a co-worker, they would know just by the look on my face if i didn't tell them!!! but i've never had this sort of thing happen to me yet.....
Well: I would probably try to figure out what I did wrong...hehehehe (make it worse) hehehehehe...then I would definitely have to tell them cuz I really made a mess by then....hehehehehehe
