The way he shrugged it off and didn't react in the slightest certainly suggests this. The bloke did behave like a knob and Leeds probably should take some action against him but I'm not sure why people are getting their knickers in such a twist about it.
Because where does it stop?
Seriously, Uwe trips backward bangs his head on chair or worse, alternatively the wheelchair user topples over and is injured......
This behaviour is unacceptable and the individual punished.
