store front name?

In the trivia for Mallrats, the Eden Prairie mall used in filming is said to have had several empty stores that were dressed up by the film crew to appear as operating stores.

One of the stores in the background of many scenes has the name, "Rug Mun..." or "RugMun..." as the store's name; the store name in large letters runs across the top of the store entrance.

The last letters of the second word are never shown, since the camera location was not changed. That allows the audience to see the store's partial name several times, with the end of the store name always hidden by other stores or the escalator.

Was that done to see if any audience member would figure out the store name?
