What am I drinking

Like most of you know I've held down the same job for more than a year now, and over that year I have used many of the little sandwich stores in the area, but like always I found what I like and give all my attention to them, ignoring the others completely. Temples has become my sandwich store of choice, why? Well not because theyre the cheapest, well actually yeah because theyre the cheapest, but also because they got me eating Tuna and cheese pannini's!

So today I'm looking in their fridge, trying really hard no to pick up that red little can of evil, so I opt for something that I havent seen before. Its green, says 'Sanpellegrino' on it and looks like it could be lemonade, its a rather satisfying drink but halfway through I think, 'Oh crap, what if its alchoholic!?' a quick search of the can and nope, no little alc/volume labels to be found. So what the hell am I drinking? I'm too lazy to google it, I'm just gonna tell myself its mexican lemonade.
