I once found a large cockroach leg in my Marie Callender's ham sandwich while eating it... Marie Callender's was never quite the same for me after that...
And speaking of Howard Johnson's, in either 1969 or 1970 when my family moved from Texas to California, we ate at a Howard Johnson's near to where our new home was. I had a waffle. It was the strangest waffle I've ever had. It was rubberized foam with no taste...
Anyone remember Stuckey’s? They were along the I40 in Arizona and New Mexico. Their "shakes" didn't melt. They stayed the same consistency no matter what temperature they were at... Not good...
