A reporter describes an incident in which they are charged the equivalent of $164 for a can of Coke at a cafe, prompting them to suggest calling police. In the account, a friend instead uses a small red book on the counter to verify or resolve the charge.

Across the three outlets, the story focuses on how a “simple system” in a European country is used to avoid or address overcharging. While the articles share the same anecdote and framing, they provide limited additional detail in the supplied text, so the specific country, mechanism of the red-book system, and any official response are not fully described.

In terms of differing angles, all sources present the same core moment—disputed pricing followed by recourse to the red book—without apparent variation in interpretation. The emphasis is on the existence of a ready reference at point of sale that can be used to check charges, rather than on legal proceedings or outcomes.

Overall, the articles use the incident as a lens to explain a local consumer-protection or pricing-verification practice, but the provided excerpts do not specify the broader context beyond the immediate cafe episode.
