Yup. Queue is a line. Cue is a trigger. The cashier can cue the next person in the queue to approach the register.

Even more confusingly, my job frequently shorthands “cue” as “Q” because it is quicker to write in a script. For instance, the script margins will have the stage manager’s notes, which include lighting cues, sound cues, etc… So the stage manager will write something like “Q136 when light switch flipped” if lighting cue 136 needs to fire when the actor flips the light switch. So they can call it at the appropriate time.

Hey buddy how's your chili doing

Oh no Sam Seder is hawt 😨

Lol what are word what does "caller" mean

Yeah messed me up that queue, que, and cue sound the same in English. Que was close enough to cue anyway
