Vinegar addict in Germany

I don't want to criticize German people but sometimes I find what they do a bit strange. Today I was in the queue at the Mensa to pay for my lunch. A student in front of me had two bowls of french fries and one bowl of raw carrots. He picked up a bottle of Balsamic Vinegar and poured it over the carrots only!

What the fuck I thought. I have noticed that I am the only person who puts vinegar on their french fries. I pour it on, point to it and say "lovely" in loud commanding English voice. I will introduce the joys of Anglo Saxon cuisine to this country.
