A cruise company was forced to apologize after employees dressed up as “upside down snow cones” were mistaken for KKK members in videos shared online.

Videos and photos shared to social media showed crew members dressed head-to-toe in white and wearing pointed, cone-shaped hats with white masks attached to them, with only holes for their eyes.

While some passengers can be heard clapping and cheering, others can be heard gasping and whispering. In a video obtained by RT.com, one passenger can be heard saying “what happened” while others can be heard booing.

After several passengers and social media users thought that the costumes looked like KKK members, P&O Cruises Australia issued an apology clarifying that the staff was supposed to be dressed as “snow cones.”
