Pub customers aren't bitter in Heineken's ad promoting its new Irish stout

It's a brave brand that takes on Guinness in its native Ireland. But Heineken is doing just that with a stout brand named "Island's Edge" that promises a taste that's "less bitter" than the traditional black stuff. The brand launched 12 months ago and now, to promote it, Heineken has launched a humorous new spot in which people are also, well, less bitter.
