Though that didn't stop someone from doing it at a college here in Pittsburgh last year. It was done as part of a one act play festival that was only advertised in the school.
I went to see it. They stuck very closely to the script of the teleplay, though the person who did it decided to add some "laughs" to the script by having all these commercial catchphrases in one characters lines. "Now can you hear me? Good." "That was Easy"
It didn't really work because it was one in a black box with minimal props. You can't really give the impression of a department store with three clothesracks that have about three items on them each.
And they cut the bridge-game song.
It wasn't worth the effort, really.
