It's been getting increasingly difficult for Andy to be seen drinking Highland Spring as so many of the big tournaments have sponsorship agreements with other bottled water brands such as Evian and Perrier. I can't remember exactly when and where it was, but I was watching Andy in a match on TV and the commentators explained that he'd been told he wasn't allowed to be seen drinking Highland Spring as it was regarded as advertising a brand other than the official sponsor. Also, Andy, like most big players, tends to drink his very specific formulated energy drinks throughout matches, we all saw the big bottles at the AO final marked clearly Set 1, 2, 3, etc - no Highland Spring labels in sight.
Thanks for the reminder. Evian seemed to be high on his preference list, so that could well be a big factor in HS's decision. No firm is going to continue sponsoring a sportsperson who doesn't flash their brand labels around at every opportunity.
Just thought I'd throw in the behaviour thing, though. What HS may have found acceptable from an 18 year old may they may not have been so willing to accept from a 23 year old, especially as expected results weren't always forthcoming.
However, my cousin's eldest son works in LA for Entertainment 19 on the music side of things, and I can assure you that they are a very
high-powered organisation, so it could also be the case that negotiations for a renewed contract simply fell through.
