For being a convenient store, it's pretty damn inconvenient to walk through 109 degree weather all the way and back for a damn receipt. I'd like to track fuel milage with paper, but I'm not going to sweat my balls off to get it either. Hey, it's my choice. So it's mutual between me and the store. But if you really want my attention to come inside, BE HONEST ABOUT YOUR INTENTIONS. I dunno, say, offer promo or discount for taking the receipt inside. But if you're not going to print my receipt when I asked it to do so.
Normally I shrug this stuff off as strange and an unusual intermittent issue. But i've seen this behavior happen all too often. It's a scam-o-ramma.
