The dad was probably short tempered because the child ill behaved or something. This line is de-contextualized, we cannot judge the man.

This is nothing near a father who hit (many times) and yelled at a little baby, almost a toddler, who was seated on the food table of a restaurant, because the angel touched the food plate being served hot!He was excited to see food, he must’ve been hungry.

I wanted to toss the hot food in the old man's face! But just couldn’t!
