When a passenger boards the vehicle, what is the standardized polite greeting and safety prompt required by professional service etiquette?

1. Greet the passenger aggressively and ask how much money they earn
2. Greet the passenger politely ('Hello / 您好'), confirm the destination and pickup identity, and kindly remind them to fasten their seatbelt ('Please fasten your seatbelt / 请系好安全带')
3. Remain completely silent and stare at the passenger through the rearview mirror without speaking
4. Complain about high fuel prices and demand an immediate 5-star review
