Missing a bus by 4 minutes and sleeping in an airport is not bad luck, it's poor planning. If you're catching a $28 bus to save cash, you already know the schedule is tight, so why roll up 3 minutes before it leaves? Get there 30 minutes early, grab a coffee, and you're not curled up on a bench at 2am using your backpack as a pillow. $28 is cheap, but a night in the terminal costs you way more than that in lost sleep and sanity. Next time set two alarms and treat the bus like a flight.
