Just ask the pax about how they want their service to go before pushback
Many other airlines do that, and it works way better than not asking.
Ask prior to take off about :
- beverage service, what beverage and when
- dinner service and choice of meal and when
- breakfast service and choice of meal and wben
- whether to be woken up or not
- whether they want a fast service or a slower service. I hate how dinner service on Air Canada takes forever in a long haul flight.
- whether they are interested in duty free
If necessary, put it on a menu card to check off (like breakfast) so it is accurately performed. When you tell one FA or one SD a preference, I find it is not always uniformly performed or communicated throughout
