I make a over the road banner every year for a community health center, they call and set up the dates the banner will be up with the city, they pay the $50 for it to be hung. Well this year I make the banner drop it off and then get a call from the city, they said sorry but that section of the street will be closed for the next month for rail road repairs. So I picked the banner up from the city and gave it to the health center.
I still charged for the banner but it was never used.
