In the old days of adverts in the paper and dodgy descriptions, I walked many a time.
To the OP, it’s not just about Bait & Switch, if you’re not into the SP then don’t go through with it.
A bit research beforehand reduces the risk of needing to walk.
And I’d suggest being realistic in your expectations, you may think you’re going to see Snow White, but remember, she was related to the ugly sisters.
