They've changed the design of cherry coke bottles so they're now almost completely identical to normal coke - there's a thin band of slightly-darker-reddish-purple around the top, and a little picture of a cherry somewhere, but that's as far as it goes for differences. The practical upshot of this is that now whenever I buy cherry coke, the shopkeepers ask me "You know that's a cherry coke, right?"
Clearly they've had lots of complaints from customers who thought they were buying normal coke and ended up with horrid cherry flavour instead. Personally, I always drink the horrid cherry stuff if it's available (indeed, as I've lamented many times before, I'm chemically addicted to it and it's rapidly sending me to an early grave. Nobody cares.), so I resent the suggestion that I'm so stupid as to accidentally buy the wrong kind of coca-cola. What kind of a fool do all the local newsagents take me for?
