Something similar happened to us at Red Lobster. They sat us all the way in the back, near the lavatories, where there was a constant stream of people. There were other open booths in the central area. OK, we didn't like it but thought it was just bad luck of the draw. Maybe they were trying to even out the load on the waiters.
Next time, we were seated one booth up - still a lousy setting. I didn't want to make a scene at the restaurant, so I complained on YELP about seating senior citizens out of sight of the younger crowd. I got a call from the manager who claimed that wasn't the case and offered a free meal. We turned it down and said to just stop the "non-existent" practice.
We go there once a month because of their "Endless Shrimp" Mondays and they lose money on me - I have no shame.
The next time we went, I was on Full Alert, but the sweet young thing gave us a window booth in the center section.
Just to play safe, I now point out the booth we want when it looks like we're being herded to the back. Always get in the center section now. Would go back if it wasn't for those damned Scampi Shrimp.
Now that you mention it, the same thing happens to us at Red Lobster, but we only go there about once a year, or so...............
