Id like to take the topic of the role of a purser and briefly break down the procedures and responsibilities in the cabin related to customer service and safety.
It can be broken down in to 3 phases
Preflight. This is the time where it is important to get organized and get all your ducks in a row, so to speak. Check your emergency and safety equipment for proper operation, and expiration dates. Possibly prepare a menu, obtain a trip sheet to get trips details. Complete a cabin asset checklist.
