This challenge was part of His Radio's. This was probably the most awkward of all 30 rejection challenges. The man could tell we were filming something and I think it made him very nervous, which made me nervous. He didn't seem to be super happy about it at all, but he let me pump his gas. I explained to him afterwards that it was part of a rejection challenge.
I think this challenge would of gone a lot better if I had approached him on my own with a hidden camera versus it being super obvious what it was. I was also talking to the radio station during it rather than interacting with him, which I tend to prefer. I've come to discover that you have a higher chance of a yes if you interact more with the person who you are requesting the favor from.
