I dined at Maza in mid January. I used my Mileage Plus debit card and I ended up having to send it a copy of the receipt. Based on my past experience, I'm guessing the manager/owner decided to try to deny me my miles. He must have figured that I was likely to be an Idine person b/c I was using a Chase UA miles card.
I still think this is a good restaurant. You can't bet 20 miles/$ and the food is great, but I get annoyed with having to get miles manually posted.
