A passenger on board an Emirates plane filmed a flight attendant pouring a glass of Champagne back into the bottle.
The passenger shared the clip on Instagram with the caption: "Emirates accidentally got into the frame, did not even notice at first. Is it the norm to dump the undrunk champagne back in the bottle?"
A lot of people - you know the type - expressed their shock and disgust at the idea that business class passengers might be served other people's leftovers. Others thought she might be saving what was left to share between her and her friends.
The clip was then shared on Reddit - and this is where we might find out the truth behind this troubling footage. One user, who claims to be a flight attendant, posted: "What I think is going on here is that the attendant is probably pouring the unused Champagne back in the bottle before take-off, to then dispose of once the plane takes off.
"We're not allowed to pour things out while we're on the ground. I bet they're pouring it all back in the bottle so they can then pour it out at cruising instead of dumping it all in the trash can making it all soggy before take-off.
"I could be wrong but realistically that's probably what's going on."
A second poster wrote: "As an airline employee... there is no way they are taking it for themselves or saving it for later (against health codes, employee rules.)
"She is almost certainly pouring the leftovers back into one container and then will go to the lavatory and pour it all down the sink at once."
And many other people seemed to agree. Like how you can't use toilets on trains when they're not moving, except less gross.
I also think it's important to point out that whatever is happening here, this woman has mad skills, because pouring anything fizzy back into the bottle without pouring it all down yourself is near impossible.
A spokesperson from Emirates told MailOnline: "Emirates always strives to provide the top quality service. Actions recorded on this video do not comply with our quality standards. We are currently investigating the incident."
LADbible has reached out to Emirates for comment.
