I haven't had a great experience with the generous customer booster. But I gotta say, I'm having a really good experience with this double coins reward.
I didn't know it was active until late last night, so I didn't do more than a couple orders. But today I've had crazy good paying orders. I don't really "need" coins right now, but I've increased by 60k+ just today, which is pretty ridiculous. On top of that, I've had orders I can fill coming nonstop, so that I was able to complete the 30 minute achievement for it, which is hilarious. I never expected I would complete that achievement ever, because of my normal playing style. So that's interesting. Yay!
