Did she “have a right” to do this?

I know this is OBVIOUSLY a life-changing debate here in CC 😂, but in all seriousness, I wondered your thoughts!

Original tweet:

At first, people were very quick to applaud her level of pettiness (and also lack of aggressiveness, unlike the other lady):

While others didn’t approve of her response:

So, what are your thoughts?

Did she have a right to do that?

Does it depend on in what way the lady was rude to her?

Does your opinion change based on whether you’re the OP/person in line or a bystander?

And what would you have done in her situation?
