I have no idea if it is related in any way or not, but in Russia a kettle is used to signify a beginner or inexperienced person.

(It is a teapot, or "chainik" in Russian. But the word "chainik" is also typically used for kettle).

It is so widely used that new drivers often put a card with a symbol of a kettle in their back window (in a "baby on board" style) to warn other drivers that they are inexperienced. And you can call anybody a "chainik" to indicate that they have no idea what they are doing. It would be absolutely normal to say that somebody is a "chainik" in the airport if they had no idea where they are going or what they should do.
