Plural of walter, referring to male servers in restaurants or the surname Walter.
From Germanic Waldhar, meaning 'ruler of the army' (wald = rule, heri = army). The occupational use comes from the formal nature of table service requiring authority and command.
The name Walter has an amusing linguistic journey from 'army commander' to 'table server' - both roles require managing resources and maintaining order, just on very different scales. Many famous Walters have embodied leadership, from Walter Cronkite to Walter Disney.
