I agree. Anyone drinking that needs to be buried neck deep in box jellyfish.
Found the wiki link about the German drink:
The Radler (cyclist) is a beverage consisting of a 50%/50% or 60%/40% mixture of lager beer and German-style lemonade. It was invented by the Munich gastronomer Franz Xaver Kugler in September 1922 when approximately 13,000 cyclists visited his tavern. His beer started to run out, so he cleverly mixed the remaining beer with lemonade and pretended he created the Radler especially for the cyclists so that they could ride home without the risk of falling off their bicycles. Nowadays the Radler is not just drunk only in Bavaria but across Germany and Austria. During the summer months, Radler is very popular there due to its reputation of being a thirst-quencher.
