first come first served

Earliest gets it

First come first served describes allocation based on order of arrival—whoever shows up or requests something earliest gets priority.

The principle governs queues, limited offers, and scarce resources: Seating is first come first served, Tickets are available on a first come first served basis.

Sometimes hyphenated when used as a modifier: first-come-first-served seating.
