Electoral scam without a voting curtain
It may seem silly, but there was a time when voting was not secret, and it was very easy to persuade someone to vote for whoever another person wanted simply by watching who they voted for. That is why, even if it is just an anecdote now, it is necessary to demand that the voting area be private, with a curtain, and that it allows total privacy, meaning that it is not possible to see who is being voted for from the sides or the front.

A school in Dénia did not have curtains for voters to take the ballots. This circumstance caused the opening of that polling station to be delayed by fifteen minutes, the time needed to obtain and install the curtains.
