IMO, it is mainly moron owners not having a clue. However, I would also say that this setup seems to be in places using a "bar with strippers" business model instead of a "strip club that has beer on hand" business model.
For example, consider Cheerleaders Pittsburgh. The two main stages are inside the two main bars requiring the dollar toss shit. Third stage is sort of a strip connecting the two where there is about 6 stage side seats. Clearly it is not illegal to have stage side seats at this location. FWIW, there also doesn't seem to be tip parade afterward, mainly only the tossed tips.
Another similar example, Savannah's Harrisburg. The stage is shaped like two overlapping circles (like the master card logo). The lower circle has stage side seating where the dancers are mostly covered, but not always and tits in face is know to happen at the lower stage. The bar takes up about 80% of the circumference of the upper circle. Many customers dollar toss over the bar, but there is one f-ing chair at the upper stage that isn't affected by the bar stand off.
To be fair, I could be more forgiving of the stage inside the bar setup in certain areas where a standoff is required by law (for example the moats around stages in some so cal clubs)... but I think the places I've seen stage moats were also all no alcohol allowed.
