The footage was posted on Facebook on Sunday showing a young man plunging his hands into a live lobster tank, taking two and fleeing on foot.
The man is quickly chased out the door by a staff member, yelling for him to stop.
The person behind the lens, who appears to know the thief, laughs as the seafood robbery unfolds.

The video appears to be shot at the Golden Century Chinese restaurant on Sussex St in Sydney’s Chinatown which closed during the pandemic in 2020, suggesting the video is some years old.
As listed on the Golden Century’s menu online, the lobsters were likely southern rock lobsters from either South Australia or Tasmania.
The price per kilo dropped to just $40 per kilo in early 2020 as the pandemic cut off produces from the demanding Asian markets.
But in late 2020 and 2021, the sought after seafood reached prices as high was $90 per kilo as exports came back online.
The two large lobsters the man stole appear to be between one and two kilograms worth of the expensive delicacy.
