Serious question, did a stranger on a plane give you advice that actually stuck?
A guy next to me on a flight to Phoenix last year told me to stop folding my dress shirts and start rolling them, and I fought him on it the whole way. Did it anyway for a trip to Austin 3 months later and not one wrinkle. What random advice did a stranger give you that turned out to be dead on?
My seatmate on a flight to Denver 4 years ago told me to freeze my jeans instead of washing them every time. I thought it was the dumbest thing I ever heard. Tried it on a pair I wear maybe twice a week and they lasted way longer before fading. Still do it, my wife thinks I'm nuts but the denim holds up.
