While I was in the hospital I noticed that when you press A on some of the ATM's it make the push sound. I looked for ever for something that it may have unlocked. Could not find anything so after I finished the mission I left for the wasteland. As soon as I left I realized that I missed a collector card so I turned right around and went back in the hospital the back way. When I got in I noticed a pile of treasures with three sticks with skulls on them ( like the ones in the sewer ). There were like 25 piles in all. So I think when you click on the ATM's it activates the treasure. Has anyone noticed this?
