Irish Rail passengers were left angered after a promotional video for a nightclub posted online captured commuters walking through Dublin's Connolly Station.
Some people were seemingly unaware that filming for the video was taking place.
Footage for Industry nightclub's promotional video was shot in the north inner-city train station on Wednesday morning between 8.20am and 8.40am, during a peak-time for commuters.
The clip shows Vogue Williams performing a brief DJ set as scores of people walk through the station's concourse.
However, concerns have been raised about the use of people's images in the short clip posted on YouTube, with just two A4 sheets posted on the station's entrance doors notifying passengers of the filming.
The notice said that the area was "being used for filming" and that by the virtue of people being in the area they acknowledging being informed that they may be photographed or recorded.
"Further, by your presence here, you grant your permission for your likeness and voice to be included therein without compensation, credit or consideration," the notice added. "If you do not wish to be photographed, recorded or appear under these conditions, you should leave this area immediately," it added.
Irish Rail passenger Izzy O'Rourke, who noticed the signs in Connolly Station, said that people "should be entitled" to walk through the station's concourse without being filmed.
The commuter stated that she "looked like the wreck of the Hesperus" but was not concerned if she was personally in the video.
However, she did take issue with the notice that had been placed at the entrance of the station informing people of the filming, saying: "I was coming into the station and I was having a quick cigarette when I read the notice, which was an A4 sheet taped to a door.
"No attempt had been made to provide an alternative way. I had a giggle about it with a few people this morning but most people who came through didn't see the notice," Ms O'Rourke told RTE Radio.
"If somebody wants to walk through and get their train I think they should be entitled to. There was no visible filming going on, but you did feel like you need to be careful of what you were doing.
"This is a commercial transaction to promote commercial entity and I feel it should be people's choice if they want to promote a particular business."
A spokesperson for Irish Rail confirmed that a brief 20-minute filming session took part in a small concourse of the train station, but added that permission had not been given to display the two A4 notices.
The company also stated on the filming "was only in a small area of the station" and that it did "not impede access or egress to and from trains". Industry nightclub said the event was "about having a bit of fun", claiming it put a "smile on peoples faces".
