Two old geezers are stubborn & irritating others, for window seat in train.

Recently, i returned from my native via train. Unfortunately, i didn't get confirmed with my berth. So, i had to travel in Unreserved coach.(not my 1st time, it happens often in my case). Later, 2 old ladies (above 60 for sure) got onboard in the next station. Next, In the upcoming station, two window seats on both the sides will become free.so the rest of the members on the aisle will supposed to move towards the window, right! Those 2 ladies got seats free at the corner already and they don't want it seems. But these ladies are literally arguing, with a sarcastic chuckle in their face, And finally compromised the guys who are about to occupy the window seats on one side, the guys sitting on other side is not leaning from their decision. Do you want to know the reason, what those 2 ladies said? We have a leg pain & the leg is being swollen. If we sit in window seat, we are comfortable by keeping our legs in parallely opposite direction. But during the entire journey, they never kept their leg on the seat with eachother, rather sat like they owns the seats. Not even showed any gratitude like thanks atleast. The guys who were about to occupy the seats, were only be able to sit in the luggage space, (above the seat). This place is not suitable to sit. Do you guys also get annoyed if you are in this situation or am i over reacting?
