The students learned the proper way to eat an egg. A German custom is to serve an egg with its shell in a tiny cup. The tip of the shell is cut. People eat the egg out of the shell using a miniature spoon. Another table side mannerism is to set a coaster on the top of the glass if you are through drinking.
Some restaurants have English speaking waiters or the menu is translated into English.
If not, Reschly acted as the translator. But Reschly is human and made an error when ordering. He and another student asked for a fish dish, not realizing it came cold. Neither could eat the dinner. Although a language barrier did exist, three of the seven students had had some German speaking experience.
