Try this
- Compare each person’s likely arrival with when they need to eat.
- Agree on portions, storage and any cleanup rather than assuming the later person wants the same meal. Keep uncertain arrival estimates labeled as estimates.
A worked example
“I’ll eat at seven and keep yours aside if you arrive later.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Base the plan on practical needs rather than requiring matching mealtimes.
