They ID In Germany???

It was a day like any other day when you are waking up in your own bed rather than a hostel bed. We got up, caught up on some of our shows we have been missing since we arrived in Germany such as House, Grey's Anatomy and Desperate Housewives. We keep getting this feeling of "Don't stay in the house, there is limited time and so much to see". We forget that we have a long time to do all those things and if we take it a day at a time, we will have more than enough. So after lunch, we headed out to Old Town again but this time, we went down a street full of stores. Steph was on a quest for pajama pants and so after searching stores for an hour, we found a store and they weren't too expensive. We also found an English Tea House and so Steph went and bought some Green tea. On the way home, we stopped in at "German Costco" and attempted to make our favourite meal Currywurst. We got home, put all the groceries away and promptly forgot the drinks. Off to the Penny Markt for us! Once we picked up our (my) juice, we spied a couple coolers on the shelf and thought to ourselves "Why not?". At the counter Too Much Foundation Turk Cashier asked us "Ausweis?" To which we responded with blank stares. She repeated herself and I asked if she spoke English and being as helpful as she was, shook her head and repeated herself. Thankfully, Woman With The Baby in the lineup spoke English. Turns out we needed ID to buy the 5.9% cooler. Steph said she didn't have ID but that she was 19 which, strangely, Too Much Foundation Turk Cashier took as sufficient evidence of our age. We left the store feeling very confused as we had never been Id-ed before. We went home and looked up the age limit in Germany and the cashier must have thought we were 16. We were shocked to say the least. The Currywurst turned out alright but we picked the wrong sausage. The cooler turned out to be a nasty carbonated wine cooler...Germans sure do love their carbonation. We had bought some DVDs earlier in the day of popular movies at home that we could then watch in German. Our landlord had provided us with remotes but not batteries in said remotes. We couldn't manually get the machine working so we will pick some up today and then begin our German immersion. It was a very quiet night followed by a pretty quiet day.
