Mobile phone footage posted on YouTube features a man complaining about being told he could not buy more than 10 bottles of flavoured water.
It shows a police officer attending in response to an argument between the man and a security guard about whether filming is allowed in-store.

Police referred the case to the IOPC on Friday, after receiving a complaint alleging excessive use of force and discrimination by the arresting officers.
IOPC regional director Amanda Rowe said the decision to investigate was taken after careful assessment.
“I am aware that the footage, which has been circulated in the media and on social media, is causing concern,” she said.
“This, as well as the serious allegations made in the complaint, means it is vital for public confidence that we look independently at the circumstances and the actions of the officers involved.”
