So far I've only had one refusal, at SJU, my home airport. And funnily enough, a CBP officer was write behind the TDC and was shaking his head the whole time at the refusal, and even nodded in approval as I explained that this is the ID I use to travel, it is an accepted ID, and it says so right on their website.
To no avail.
Reminds me of my travel in the USSR in late 80's !
