Years ago when my youngest was only 3 or 4 we were flying from SFO to Dulles. My daughter had been asleep for about 30 minutes, woke up and wanted to cuddle with daddy. So, I put her on my lap and snuggled her only to have her puke all over my shirt and seat. NASTY!!
I had no clothes in my carry on and the plane was full so there was no changing seats. The stewardesses gave me a bunch of paper towels and I cleaned up the best I could but I reeked. I think Frito Chili Cheese chips are nasty but when there is puky-ness mixed in, that's super nasty. Still won't eat them.
Had almost 3 more hours of flight time when this happened. I'm gagging typing this.
