Some of the generally accepted rules of plane etiquette include not taking off your shoes and not invading other passengers space.
But one horrified easyJet passenger caught a couple breaking both rules after she saw a man 'picking dirt from under his partner's toenails' during a flight.
Erin Butcher was flying home from a seven-day family holiday in Tenerife but was shocked to notice a woman's bare feet propped up on a tray table.
The 27-year-old was then left 'disgusted' after she noticed a man appearing to pick at her French pedicure toenails before 'flicking bits of dirt' to the floor and over the seats.
Ms Butcher claims the couple did this for 20 minutes, while other passengers laughed nervously in confusion.
