Im Restaurant

Today we learned to make indirect questions:
For example:
Hast du schon mal im Internet Bücher gekauft? -> Ich habe gefragt, ob du hast in Internet gekauft. (verb sthet das Ende).

We have learned from the adjectives variations by gender and whether the adjective is part of AKK or Dativ.
As configured diminutives of nouns: Bierchen (-chen) and Fräulein (-lein)

Finally we have learned to behave in a restaurant. Demand the beverage, food, and pay. First the teacher pretended to be the waiter and then one of my colleagues.
