Stephen McMenamin, a former U.S. Marine, was there for treatment, and said his wife took the pictures because she "found it upsetting."
McMenamin said a veteran who was lying on the ground was using his bag of medication for a pillow after being denied an available reclining chair.
"The nurse started yelling at him, telling him he can't do that," McMenamin said. "He's, like, 'I can't get up and I won't get up. I will be here until you can see me. Can I please have a blanket?'"
