Wearing very expensive formal wedding outfits, Bri and Lottie are feuding wedding caterers who have brought their wares to pitch for business. But when Bri accidentally pies Lottie, a tit 4 tat pie fight is on. Pie sandwiches, custard, trifle, gunge, chocolate porridge, cream, custard and so much more are used by the girls, while onlooker Willow just laughs at them. The girls end up losing their outer layers, and going down to their slips etc. Their (genuinely) expensive formal outfits are totally ruined, and the final humiliation is an eclair stuffed in the mouth for each girl.
