"Happy shopper" ones are even worse I dont know how they got so much pee from one cat! then to make it worse they added about half a pound of sugar! - (to the drink not the cat).
Exactly, for colour.
Have you heard about a "drink" called the Messerschmitt?
"Invented" by the Polish fighter pilots during the BoB.
It consisted of everything that could have been found in the bar (vodka, brandy, whisky, gin, beer, cider etc).
Personally I just can't imagine such mix, its "taste", colour...
