Barclaycard: “Waterslide” [01:30]# Payment using the new Barclaycard is such a simple, no-fuss business that it is like slipping down a waterslide. As seen in this commercial, in which an office worker, rather than going by elevator the way his coworkers do, takes the waterslide, which begins in the storeroom and leads all the way across town to his home. On the way, he does a little shopping, checks into the subway – all of it child’s play with the card from Barclays. VO: “Making payment simpler.”
