I bought a Mars Bar recently out of curiosity. I’d forgotten how bad it tastes, a foul combination of warm cough medicine and a sickly sweet dollop of gooey Pepto-Bismol guaranteed to make you feel sick. Reminded me exactly why I stopped eating this crap excuse for chocolate thirty years ago.
As for the laughably rubbish tagline, I doubt there’s any person for whom a Mars a day helps them work, rest and play. Unless they’re the type of idiot who thinks hot women sit around in their undies all day eating Cadbury’s Flake.
