They are not trendy.
So I was surprised the other night to see posters advertising them all along the Underground, obviously aimed at the busy young professional.
The slogan was '91 calories, tastes like 900'. Fair enough. Unfortunately, it's easy to misread as '91 calories, tastes like goo' - especially if you're a bit drunk, as I was.
I have not been blown up. Hope you haven't either.
