As stated elsewhere, I will do as many of these as I can grab, regardless of the fee.
I just knocked out 8 yesterday with the fee up to $25, plus another 2 I had pre-booked at the normal $8.50.
Interestingly, remaining shops are now showing a $16.50 bonus instead of the increased fee.
I just don't get people's hangups with the conditional reveal.
Do you do "normal" gas station shops, where you have to reveal regardless?
I see no difference between the two tasks whatsoever.
I just tell the clerk I'm doing a quick merchandising check, ask about the gift cards (or mention them if I've already seen them), ask a filler question about alternative fuel types available, then ask if I can get the photo. Sometimes they might comment about a missing name tag, but I typically get no resistance unless it's someone who would not want their picture taken regardless of the scenario.
Have synthesizers, will travel...
