About some comments above:
He was not an employee of the hospital but the father of one,
He has a cognitive impairment, not a mental illness, so who knows what medication, if any, he is on. And it looked like he was drinking light beer.
I don't know about his keys and wallet, but he did take his beer with him.
83 and nursing home? He looked quite sprightly for an 83 year old everything else considered.I hope I can keep going to games when I'm 83 (whether I remember the game next day or not)
And, yes, Thornton did conduct himself well. You think that he would've been within his rights to lash out, but imagine the fallout if he did then everyone found out it was an 83 year old with cognitive issues. Eddie McGuire would've had a field day!
