was i wrong in this situation?

i have a money order that was mailed to me. we went to a grocery store to cash it and the employee said “i’m sorry we don’t cash postal money orders here, we only cash money orders from *store name*.” my dad responded with “on google, it says you do. why can’t you just do it?” and she says “sorry sir, that’s our policy. i’m not sure why it says that.” and he was visibly frustrated and said “but why?” and she said “i’m not sure but i can get you a manager.” he said “no, whatever.” and started to walk away, but he then walked back and said “i don’t get why on google it says you cash them but you don’t.” she again asks if he would like to speak to a manager and he said “no, whatever, f*ck that you guys suck”. after he said this i tapped his arm and told him to stop, i was anxious and just wanted to de-escalate the situation. we get outside of the store and he says “don’t you ever do that to me again. don’t defy your parent for some stranger. what makes you think that’s okay to hit me infront of someone?” (i didn’t hit him, i tapped him). i apologized for what i did and said i shouldn’t have done it. he said “i don’t want to hear that, i want to know what made you think it was okay to act like that”. now he’s not speaking to me. i just want to know if i was being out of line for what i did.

It sounds like your dad has anger management issues.  You did the right thing at the right time.

I'm going to go against the crowd and say yes you were wrong. Your father felt like you were showing disrespect to him in front of a stranger. You really had no reason to even speak up at that point. If he doesn't walk away after that comment that might be different. If you really felt the need to speak up you should have said that the manager could explain the policy instead of just telling him to stop. I understand most want to say you did nothing wrong, because what your dad did was wrong first.

I see no problem on your part.  What does your mother say on the subject?

You didn't do anything wrong. Your father seems to be a hot head but you sound like you're not going to be that way, good for you.
