I've found out a bit more about this business of customers having to queue up three times to pick up items they've reserved. It turns out that the problem isn't that staff were putting their backs out bending under the counter to get the books off the reservation shelf. The problem is that (presumably female) staff wearing low-cut tops were complaining about customers looking down their cleavages.
To be fair, there are some pretty impressive decolletages in the lending library. Even so, I can't help feeling they're solving the wrong problem.
We ought to be issuing counter staff with modesty bodices.
