However, you might be skeptical of their lack of official credentials. Would you prefer to speak to a certified expert in travel who has never made that particular journey?
A particular expert is available who insists that around 15 years prior, they had studied a map of that general area and then were tested within a famous university to confirm approximately 3 details of what was on that map. The map itself was already 10 years old, making the contents of that map now 25 years old.
They received a passing grade on that test (which included many other items besides approximately 3 details about that map). They have a certificate on the wall that they earned through passing that test and many similar other tests.
They are also certified as an expert in travel by their local church (because they have interviewed over 100 people who have actually done some traveling, asking each of them 6 pre-formulated questions about their travels). They have never done any traveling themselves, mostly because they think traveling is generally a bad idea and not worth the risks and potential confusions and complications.
Considering all of this, how could you risk insulting them by even considering a conversation with anyone who does not have any official credentials? Unless you are actually interested in getting to your stated destination, then you have every reason to disregard the person with real-life expertise and instead have some tea with the certified travel expert and cancel your plans for that silly trip (which has not even by authorized by the oversight board of the local church)!
They have a catchy slogan, too. “We are the only experts in making oversights.”
