McDONALD’S has apologised after setting up video screens showing a sports channel for customers - not realising that in the late evening the channel switched to broadcasting porn.

The hardcore broadcasts went on for some time, luckily in front of an all-adult clientele, before staff in the Swiss fast food store noticed.

The incident occurred in Zuchwil, a town of about 8600 in the Swiss area of Solothurn.

Diner Steffen Reiniger went to the restaurant with some friends for late night burgers.

“We were only a group of men so it didn’t bother us, although what would have happened if there was a family in the restaurant at that time, I don’t know?”

An employee finally noticed there was a problem and changed the channel.

McDonald’s said employees were asked to leave the TVs turned to the Eurosport channel, but sometimes workers “change the channel to please a customer,” McDonald’s spokeswoman Aglae Strachwitz revealed.

On this occasion it was changed to a different sports channel that, unbeknown to the staff, also included a porn show. She said the mistake was pardonable.

“If our employees didn’t immediately realise what was going on it’s because they were concentrating on our customers and their work,” she said.
