It is a mystery to me how one should be able to make any money at all with the product discussed in the below clip -- it just tastes awful. By contrast, milk is one of my favourite drinks. Also, the best energy drink I know is mate tea. Or a drop of vodka. But only a drop.
Mind you, Austria can be a funny place: you arrive at your ski resort, happy to take a breather, on the drinks menu you are being offered a fancy sounding drink which consists of whiskey and Red Bull. You order the oddity and are promptly served a glass of whiskey and a can of the energy drink. So you open the can and pour it into the whiskey. When you get to sip the drink and dreamily study the inscription on the can, you learn that it is illegal to mix the energy drink with alcohol. Which is oddly constricting, as the drink is only drinkable when heavily diluted with whiskey. In the meantime, you are left to reason - since it is me who has committed the mixing act, I suppose, the restaurant proprietor is off the hook, and full legal responsibility rests with the hapless foreigner.
I could talk for hours on the masochism of being a German spending a holiday in Austria.
As for the below opinion, while I regret the language used in certain passages and doubt the gentleman's economic literacy, I am impressed with the show of character and share with him a robust dislike of the beverage.
