What is a "glue shelf"?

Have you heard of such an expression for perhaps a large exhibit shelf in a mall or shopping location?

I assumed so because the original context goes as "I stood in fron an enormous glue shelf in the freezer section looking for small eternities." and that is somebody's experience at a shopping area in which, I also don't understand what "small eternities refer to.

I suppose this is a British expression since the article was published in a Singaporean magazine.
