...wait, are we really overthinking joint size this much? I get that Denver corners can be finicky with humidity and all, but I've seen guys get clean lines with everything from a tight 1/8 to a big 3/8 just by adjusting their speed and pressure. The whole "skinny joint is gospel" thing feels like one of those rules that gets repeated until nobody questions it. Your mileage may vary obviously, but I'd bet most of the difference came from you being more careful since you were trying something new.

Haven't we all worried when something works a little too well for no reason?

Yo I feel you on this so hard. I've been doing the same thing with Fetch and I swear I only get like $2.50-$3.00 back after scanning a bunch of receipts from the same gas station near my place in Denver. It's not life changing but it's better than nothing, especially when I'm just trying to fill up and get on with my day. The data selling thing kind of creeps me out but I figure they already know what I buy anyway from my card transactions. Honestly if someone told me I could get a free coffee every couple weeks by just snapping a photo I'd still do it.
