Had a little incident at work today. When I ment to take 50 percent off on a bread I accedently took 50 percent off the whole receipt, and there was no way to undo it!! I called on a co-worker for help but she did no know what to do either. Apparently it had never happened before. Do not ask me how I managed, but somehow I did. Finally my supervisor was able to clear it out. Prror to that there was a lot of sweating. Oops :$
