The last time I was in a Dennys, I think it was Buena Park, CA. I called it, (no Bueno Park). I happened to look up above our table, and saw the perfect silhouette of a rat walking on the transparent plastic neon light cover. We got up and walked out before they could even take our order.
Maybe the rat was identifying itself as a Human Democrat voter. 🤓
In 1990, my hometown had a Denny's. I ate breakfast there one day, went to work, and went to have Dinner with my gf and we wanted to have Denny's, it was closed. My friend (who worked at the Denny's) said, the company told customers to leave the restaurant. Some were in the middle of lunch.
