See those thing here?
It's a sanitary pad. In other words, the magical blood catching pads that many women use during their periods. Well, one of my extremely close friend who worked as a flight attendant once got into a heated argument with a guy who insisted to have EVERYTHING. Anything, that was free or complimentary on the flight, he wanted it. He was extremely annoying constantly kept on bugging the flight crew for stuff. If he saw someone next to him get something, he wanted it too.
At one point, a lady asked for sanitary pad to help her 'emergency situation'. He insisted he should have one too - cos you know, it's free, right?
My friend tried to explain and reason with him. This guy spoke Russian and his English wasn't 100%. He kept on adamantly insisting to have "one of those" and seemed to assume the pad was one of these..
A sleep mask.
My friend got him his pad and upon receiving his sanitary pad he cheekily proceeded to peel the paper backing off and expose the sticky side; he stuck the thing over his eyes and soon afterwards fell asleep...
