Far from the only example, but this one at The New Republic just kind of jumped out at me this morning.
Many are unaware of the subminimum wage that allows a tipped employee to be paid as little as $2.13 per hour.
Then, in the very next paragraph, the admission of the lie:
[E]mployers are not required to pay minimum wages as long as customers make up the difference.
It's not that they're "allowed ... to be paid as little as $2.13 per hour." It's that they may be paid part of what they earn directly by the customer instead of with the employer as a middleman. The total must come to at least the legally mandated minimum wage. If tips don't get the employee there, the employer has to make up the difference.
I happen to have opinions on tipping, but I'm not going to go into them here. The point of the post is to point out how its opponents tell a blatant lie, then later on slip in an admission that they lied, hoping that readers are too stupid to make the connection.
