On a flight home from PVR - a dad with two children opened a jar of pickled garlic, ate about 14 cloves, and then handed it to his 9 year old daughter who scarfed down 1/4 of the jar.
The worst was when he washed it all down with a carton of milk he nabbed from breakfast at his hotel and proceeded to have "garlic belches" for the next 10 minutes. It took me that long to get moved to another seat.
