A more thorough explanation:

Definition: A purser is a person who is responsible for managing the accounts and documents on a ship.

For example, on a cruise ship, the purser is in charge of handling passenger payments, managing the ship's budget, and keeping track of important documents such as passports and visas. They also handle any customer service issues that arise during the voyage.

Another example of a purser's responsibilities can be seen on a cargo ship. In this case, the purser would be responsible for managing the ship's finances, including paying the crew and purchasing supplies. They would also be responsible for keeping track of important documents such as cargo manifests and customs paperwork.

Overall, the purser plays a crucial role in ensuring that the ship runs smoothly and that all financial and administrative tasks are handled efficiently.
