 Boarding an aircraft front to back is always a problem given how the aisle is always a mess. People are trying to get their bag in the bin above them, and they're blocking, and they're talking. And they know there's 100 people behind them, and that's when they stand in the aisle, open their bag while it's overhead, and try to find one thing while we're all waiting. Just get out of the way. Get out of the way. Take that thing out of your bag before you get on the plane. I hate you.
