Friend was telling me his recent flight with Southwest Airline. It's open seating with SW so by the time he boarded every seat was the middle seat. He sat between a mother and child. Yes they were a family with some across the aisle and mother and child did not want to sit next to each other. So for the whole flight they talked over him, passed this and that constantly to each other. Then mom passed an open can of soda to kid and one slipped, the whole thing spilled all over him. Yikes! He got up and switched to different middle seat.
Make you wonder if by using LCCs you risk bumping into the less considerate.
