We've witnessed some pretty shocking in-flight behaviour in the past but this may just be up there with the worst.
This male passenger was spotted casually watching the in-flight entertainment screen while sporting a bandage covering some kind of wound on his leg.
Not really a problem here - until you notice the wound is seeping and a yellowish substance is dripping down his leg, forming a puddle around his foot on the floor.
The gross image appears to have been taken by a fellow passenger sitting in the middle section of the flight.
It is not clear when or where it was taken but it appeared on the Instagram account Passenger Shaming, a fascinating gallery of the world’s worst-behaved air travellers.

The picture attracted dozens of comments, with many people declaring it the worst post on Passenger Shaming yet.
One person wrote: "Nope. No. Not EVER. NO" while another said: "I can’t with this … this is the worst one yet."
A doctor even responded saying: "I’m a doctor but I did barf in my mouth a little upon seeing this!!! Dear Lord let it be a Halloween prank or something.”
Other images which made it to the shaming account include a man shaving his hair in his seat, dirty toes, a monkey and someone wearing just their underwear.
