Then (some airports) there was an agent standing by the kiosks. Even when I was the only person there, the agent asked to see my freshly printed receipt, then waved me on.
Most recently (few months ago), at ATL, everyone had to go to the first available immigration agent and show receipt and passport, whether or not they got the 'X' (that hadn't happened to me before at ATL). This has happened occasionally at other airports. Not something tied directly to the photo, because it has happened before the photos were on the receipt.
At customs, I always hand the passport and receipt to the agent. Some just take the receipt and hand the passport back, some open the passport and check against the receipt. Only in ORD did the customs agent (NOT the kiosk agent) demand to see my 'CBP' sticker. (No checked bags, nothing to declare).
I also have had several different experiences depending on when and where I entered immigration. At IAD (the airport in question), there is almost never anyone around.
The point I was making is don't stop and stand there if no one is around AND there is no sign telling you to wait. At airports other than IAD, sometimes there will be an agent posted either at a desk or just standing up as you go toward the baggage claim facility. If you are asked for your passport and receipt, show it to them.
At the GE Customs line (after you pick up your baggage), you always are supposed to have your passport and receipt, and the customs officer will take that receipt.
