You are right, and perhaps more right than you know.
This story is making the rounds on other sites, including some news sites. And what's being highlighted is the tow truck driver's Trump connection, not the woman's supposed inability to pay.
Will one story like this hurt Trump? Nope. But many like it will have an impact. That's how propaganda works.
And it should be a caution for Christians who are jumping on the Trump support bandwagon. I think he’s probably going to be fine and dandy as a secular president. I’m not expecting Trump to be my godfather or my personal financial mentor, however. That answers to a higher authority.
