Postman Meier tells neurologist Professor Dr. Feurich about his problems with the angry master baker Fröhlich. In a flashback, we see how Meier first asks the baker to bake a pretzel in the shape of a 20-centimeter-high B covered in icing. Fröhlich presents him with a Latin B, but Meier is not satisfied because he wants one in German script. When the master baker then hands him a B in Sütterlin script, Meier demands a small b from him that is identical in both fonts. When the b finally turns out satisfactory, Meier eats it immediately.
