I realize we're all tired. Some of us sleep better than others. Some of us are incredibly fatigued in the morning, when we take transit to work.
And then there are some of us who decide to use a subway ride as an excuse to nap. That's fine. It happens. But when transit riders break etiquette to sprawl across a two-seater area to take a snooze...that's when I get frustrated.
It doesn't matter if there are other seats available. It's rude and inconsiderate to sprawl your body across two seats and get some shut-eye. Lean against the window, not against an available seat. Those sleepers won't notice if an elderly rider or pregnant woman walks in, looking for a place to rest their gams.
I do my best to follow transit etiquette. And it's a shame when I come across riders who don't do the same.
