Ok, I was willing to sort of overlook and/or forgive the blatant shilling of the Chase Sapphire card or whatever it's called, once (Istanbul). I don't think they did it in the Brittany episode. But then in the Prague episode, they did it again although this time Tony didn't offer a snide comment. Perhaps the producers were trying to be slightly more subtle, but I don't think that worked. It's almost like the episode was in black and white and that card glowed blue (er...sapphire), that's how much it stuck out.
For some reason this is bothering me a lot more than all the product placement that's done on Top Chef (and I haven't missed a single episode of TC or TCM since inception). Just had to vent, because I will continue to watch, but really, it's enough to make me never even consider getting one of those cards.
