I don't think you got a good answer to this question, so here goes my 2 cents. GFE is important for being treated like a king. Why men go to an SP or MPA its to have some luxury and be spoiled, as opposed to being dumped on (boss/wifey), nagged (wifey), and told or hinted what a loser they are (world). Chicks like their salons and spas to be fussed over and refreshed well guys like MPAs and SPs for the same reasons. GFE is better than cold, mechanical, or dead fish as it injects some friendliness into the event.
