My procedure is to take the photos of the outside stuff (dumpster, building, and parking lot), run the GPS verification, enter the drive thru, take those photos, start inputting the shop (if there is a line of cars), take food temp outside DT, taste the food, eject the food, finish report with pics, delete pics, record shop data on my spreadsheet, and get the bleep out of the parking lot.
I have never had an issue with duplicate photos, my only shop that I was not given credit for was one where, during my 42nd shop of the day, went to the wrong location, where two restaurants were within 0.5 miles of each other...
Oh ya, and the shop today where I took the food photos, and was so hungry I ate the sandwich, then promptly accidentally deleted the hamburger photo before submitting the report... opps... :/ (I had to buy a second sandwich for the photo... I am glad I was hungry)
