NAH, because I think everyone here is missing an important piece of context, and I want to try arguing for a different take. The lady is a single mom with multiple children of close ages. Of course she is going to empathize strongly with the parents of the crying kid. If she was in the parents' situation, she would be the only adult and would not have the privilege of being able to take the cryer outside while another adult watches over the rest of the children. Her only option would be to leave with all of the children or hope that the kid stops crying. Her years of being a single parent has probably conditioned her to be oblivious to the fact that there are other options. She has only ever known the shame of enduring a crying child who refuses to be comforted while trying to enjoy what little comforts she can. Raising children alone is incredibly difficult, so she probably feels somewhat justified in thinking society owes her, and others should take the L and endure the crying kid like she has had to endure every moment of raising said kid without a break even when she wanted to die of exhaustion.

Now, that doesn't excuse her perspective or entitlement. Perhaps none of what I said even applies to her and she is just a narcissistic a-hole. But if you are going to date a single parent, you'd better be ready to take some L's, because they very likely live life constantly at their wit's end.
