I've had some questions with Citgo pictures needing clarification. However, about half were valid questions.
The recent ones I thought were really picky were:
Did it appear the top left corner of the metal valance looked dented?
You just showed a close up of the nasty looking sink (mechanic cleaning black stains). Do you have any overall restroom pictures (I submitted three others to justify this rating as failed).
If you zoom in on the picture, does it look like the credit card application holder looks empty? Please clarify.
Please justify that there are no windshield cleaning supplies available on the island. This was at a location that I had to wait 10 minutes to exit because there were so many repaired cars waiting to be picked up and someone had left their car at the pump to do something in the neighborhood. I couldn't get around. I couldn't walk five feet away to take an island picture with the repaired cars in the way. I had taken several angled pictures. Thankfully, they accepted these clarifications.
I've done Sunoco with minimal issues. I've yet to do BP, Exxon/Mobile or Shell. Either none near me or I'm not signed up with the right MSC, and I'm signed up with 125 different MSCs.
