I do a lot of gas station audits and have got them down to about 17 minutes on site, then maybe 15-20 minutes at home to fill out the information and upload photos. First, I've made my own one page form that has room for three shops, saving me paper. The company's form is several pages and the print is tiny. Their form is horrible. I don't print their last page at all, the chart to fill in for each pump. For that I refer to the photos when I get home. This cuts the time at the store considerably. I don't know why anyone would mark these while on site, however I sometimes make notes if there's something you might not see in the photo. My photos always go in order with bathroom first, then when I get back to my car and before the reveal I take photos of the receipts. This way I don't have to worry about losing them. Then I take the photo of the employee, then all of the pumps, MID, and any infractions. I complete my shop, get in my car and put the next shop into my GPS. Then I drive across the street and take the last overall photo. When I get home I use a bulk photo resizing site to resize all of my photos in just a couple minutes. And that's it. This could be done with just about any gas station audit that you know well. Also, I never print the first page of the packet with the code on it. For that I just go to print preview and I can see the code and make a note of it, saving paper and ink.
