Long haul flights often mean relying on airline food to help get you through - and standards can differ drastically depending on who you choose to fly with.
Many of us stock up on snacks in the airport just in case, hoping that an overpriced packet of crisps and a few sweets is all our bodies need for the next 24 hours of our lives.
Having pizza on board is nothing but a distant dream for most of us, but one passenger who clearly prepared in advance appears to have saved a slice as a mid-journey snack.
At first it seems like a genius move - until you see a picture which has been shared on social media of how he prepared his meal.
Rather than eating it cold - which seems like the logical choice considering he was on and aeroplane - he decided that it would taste better warm.
Asking the crew for help to heat it up was a long shot he wasn't willing to take, so instead he turned on the overhead light above his seat and held the slice millimetres from the bulb in the hope it would cook.
The moment was captured by a fellow passenger sitting in a row behind and shared by the Passenger Shaming Instagram account with the caption: "Just warming up some leftovers."
It racked up more than 8,300 likes as others were left divided by his cooking technique.
One commented: "You can't fix stupid."
Another said: "That's an LED light. It doesn't put out heat."
But a third argued it could actually have worked, citing personal experience, writing: "I actually got burned from touching that light after hours of it being switched on."
And plenty of other people were just relieved it wasn't another picture of someone putting their bare feet on the seat in front, with one replying: "I'm disgusted but it could definitely be worse."
