Forgot to take a pic of the outside of the restaurant... TWICE. Two shops, forgot both times. Had to drive back and take the damn pic.
Another restaurant shop, I did dine in but was assigned bar shop. Luckily, the scheduler was able to switch it for me because the dine in was never assigned.
Got a shop rejected because I had googled an address and took a screen shot of the image. Accidentally uploaded that pic to the report and it got rejected for using a google image. Even though... it had nothing to do with the required pics.
Took a bite of the food before taking a pic... salvaged it by using some good photography tricks and garnish.
I am sure there are more.
