What is the significance of the title?

Explanation

The main character here is prone to create small mishaps. Especially during tour this can lead to discomfort of fellow passengers. Think for a while, you are sitting on a window seat in the train enjoying the beautiful scenery outside. Then somebody sitting on the upper birth spills his favourite curry and spoils your new shirt and your mood too. Those sort of persons are better at their homes. The way he creates accidents justifies the title, “The Accidental Tourist”.
