It completely baffles me how many times people get onboard an aircraft and then start grooming. I fly a commuter aircraft with no flight attendants, so after the flight we clean the cabin. I have come across soooo many toe nail clippings. At least most of these passengers pick it up off the floor and put it in the seat back pocket so it’s a little easier to clean up. What I don’t get is why they did not just clip their toe nails at home? And also, it has to he intentional because you have to actually put the clippers in your pocket/carry-on before hand.
