This is honestly one of the most upsetting stories I've read in a while. I've really been losing more and more respect for United Parks (Sea World and Busch Gardens) but this may be one of their shadiest stunts yet. In short they've started prompting you to tip at counter service transactions which isn't ideal but something we're seeing at a lot of places anymore but, in this case, the money you tip actually first offsets Sea World's payroll before giving some to the employees (if there is enough).

The way this works is they are functionally reducing their employees pay rate to minimum wage but continuing to pay whatever their existing pay was as a guaranteed rate. This is creating a loophole where they can take the tip money and use it to pay part of the employee's wages. The only point where extra money would be given to any employees is if the tips exceed the amount of difference between everyone's minimum wage rate and their guaranteed rate.
