OPA are nothing but obstacles to things I want in the airport. When they're ahead of me in the security lines, I just know they haven't flown since sometime in the 1990's and will be completely clueless about all things TSA. They will have worn knee-high lace-up boots and scattered twenty containers of liquid toiletries throughout their carry-on, rather than putting them in a quart-sized bag. They will also hog all of the bins. Because of them, I will miss my flight, or at least not have time to buy food before it.
When OPA get coffee in the airport, I just know they will spend ten minutes crafting the perfect order. This will spiral into even more time as the barista stops everything to make said specialty order. They will cause me to forgo my beverage or miss my flight.
I can't speak for male OPA, but female OPA are problematic even in the restrooms. When they get ahead of me in line, I just know they will inexplicably park themselves in the stall for the next twenty minutes, and probably pee on the toilet seat before finally leaving.
And of course we know that once we finally get on the plane, it's those awful OPA who have hogged all of the overhead bin space.
I laughed when I realized how I was generalizing about all OPA, but then I realized...to someone else, I am OPA, the imagined obstacle between the airport and the final destination. In the future, I'll try harder to be nice in the airport so as to improve the image of our downtrodden group.
