I went on the site a couple of days ago to make sure I'd been credited for our recent reservation only to find that I'd been stripped of the points I'd earned for a reservation from about six weeks ago. I asked them about this, and they said that it "looked like" I'd reserved from another source -- including visiting the restaurant web site and clicking on OpenTable to get to my account (which, for some stupid reason, doesn't count). I find it very curious that they went through all the motions of crediting me, ASKING FOR A REVIEW OF THE RESTAURANT(!), and then taking the points away because of this ridiculous little loophole. It's like making a purchase via PayPal, logging onto my PayPal account to pay, then having PayPal refuse to pay the merchant because I didn't leave the merchant site first and go to PayPal.
Scam scam scam scam scam.
