The woman goes on a rant about homophobia and gay marriage when she needs to focus on reporting the man's assault and battery on her 2 year old child. Bottom line, that is what crimes the man committed.
Going on about all kinds of stereotypes of the man's world views. At the end of the day he is your garden variety drunken jerk.
The store would be more than happy to review its records to see if the man checked out and paid for anything. If so, there are a variety of ways to track the man down. The man is seriously lucky he did not end up getting beaten himself if the right bystander was nearby.
God grant me
The Serenity to accept the things I cannot change,
The Courage to change the things I can,
And the Wisdom to know the difference.
