The only place where I have to show any kind of ID card is at Costco (their membership card). BJ's (a membership warehouse) is fine with storing the bar code on the phone and scanning it from there.
It depends on what kind of activities you do. If you just fill your car gas tank, or buy $50 worth of grocery, no one cares. But you almost always get car'ed and ID'ed when you buy gift card. Some stores even check cards with GC just $100.
