His "pot companion" (drinking buddy) in the pub pronounces the guide to be poor one of a "boring, expensive city," and does not understand the narrator’s preoccupation with streetcars, tortoises, or the publican's young son’s view from the rear annex.

This is exactly how the narrator feels about his own experiences around Berlin that day.
