Who dropped the bomb?

Was having dinner with family at Nando's. Got my chicken. Happily slicing it and ready to eat.

Then there was this old dude who was standing next to me, with his arse directed at my back.

No big deal, some random dude right.

Then out of the sudden, I heard,

"Pppplaaaaaaaaaapppp"

The dude farted when I was about to eat my dinner!!BUGGGER
