Booze-loving ghosts have reportedly been haunting the US-style bar and grill Witham and Blues, in Langrick, Lincs.
This latest spooky event shows a barman serving customers, before a glass smashes to the floor after falling from a shelf.
No one else appeared to be near the shelf at the time of the mystery, which happened last Saturday.
At the time, staff said they thought nothing of it.
“The owner later went through the CCTV and saw that none of us knock it over”

But a closer look at their CCTV prompted more questions.
General Manager Maddy Taylor, 32, said: “We sort of blamed each other because it was busy and we do tend to break glasses.
“I walked through at the end to just say can we get this cleaned up.
“We just carried on as normal at the time and even joked it might have been the scary lady – which my daughter said she saw the other week.
“The owner later went through the CCTV and saw that none of us knock it over.”
Last week, CCTV showed mysterious orbs floating through the air after dark.
The bar has had numerous offers from mediums to look at the bar, but the management have declined, although admit they enjoying teasing newbies with ghost stories.
“There’s nothing sinister at the moment about the presence – it just seems a bit mischievous,” Maddy told The Mail.
The building itself is more than 300 years old.
Victoria Burden, 36, who lives above the restaurant, previously said the ghosts aren’t out to get anyone because “we’ve had nothing sinister happen”.
But could the ghosts be changing their tactics?
Victoria said: “It normally sounds like a busy bar, but when we check the cameras it’s all dark and locked up.
“I like to think in general the building has a friendly feel, but more recently this area has been more ‘active’.
“Friends of mine recently sat at that table, and after a while they asked me if this place was haunted.
“My husband said he had seen her wine glass move across the table on its own when her back was turned.
“She later joked that a ghost had tried to steal her prosecco.
“We feel that any ghosts here must just be former drinkers from another time, and not out to hurt anybody as we’ve had nothing sinister happen.”
