A temporary arrangement that stayed

Text A: an original contemporary practice extract.

During repairs to its serving counter, the café placed a rope across the room to direct customers to one till. When both tills reopened, the rope remained. I joined the queue behind it until a member of staff asked why nobody was using the second till. We pointed to the route that the rope still required us to take.

The supervisor removed it after checking that the repairs were finished. The staff had become used to moving around the barrier and no longer noticed what it told arriving customers. For the next repair, they put an end-date check on the temporary signs. A route that had helped on Monday was delaying people on Friday because its original reason had not left with the repair tools.

Text B: an original contemporary practice extract.

The library reserved a row of chairs while paint dried on the wall behind them. A notice stayed on the seats for several days after the wall could be used again. Readers chose other places, and one asked whether the row was permanently reserved for a group. The assistant checked with the person who had arranged the painting.

The notice was removed and the chairs returned to use. Nothing had been wrong with keeping people away during the work; the mistake was allowing the instruction to outlast it. The library added removal of temporary notices to the completion checklist. Staff who knew the painting was finished had needed to consider what a visitor could reasonably infer from a sign still saying otherwise.
