If a consideration in employing someone at the ticket counter is that they have well-founded opinions or suggestions to offer on films, then, by way of their expert status, you've cause to believe them.
Otherwise, this collapses to a general critique of the upstream assertion: that "low-value" positions, such as box-office worker, see no labour value add, whilst simultaneously a certain set of positions, say, white-linens restaurant waiter and/or somnlier, do.
I don't see both arguments being valid simultaneously.

I'm disregarding it because it's observably not true.
People are employed at theatre ticket offices because they are teens who are willing to work nights and weekends for minimum wage, not because they're film experts.
Expecting a ticket booth employee to be Roger Ebert is about as reasonable as expecting a Radio Shack employee to be a qualified electrical engineer.
