Most people appreciate a simple thank you, but not everyone thinks it’s worth starting an argument over.

That became a problem for one man after he held the door open for a couple walking into an ice cream shop.

When neither of them acknowledged him, he sarcastically said, “You’re welcome,” as they passed.

The husband immediately turned around, and questioned what he had just said.

Before long, the man was defending his reaction and telling the husband to watch his mouth.

AITA for saying you’re welcome when someone didn’t say thank you.

My wife and I were walking into an ice cream shop on Yonge St. in Toronto.

After my wife walked in, I held the door open for a couple.

As they walked past me, they didn’t say thank you, so I proceeded to say, “You’re welcome,” sarcastically.

The other guy didn’t take it lightly.

The husband turns around and says, “What?” and I said, “You didn’t say thank you after I held the door open for you.”

He then proceeds to say, “You better look after yourself,” and I end it with telling him to watch his mouth.

I’m a firm believer in common courtesy, despite being a bit of an *******, but I do know how to function in a society.

AITA???

Wow! Bad attitudes all around!

Let’s see what the folks over at Reddit think about what happened.

This reader thinks he was in the wrong.

This guy is on his side.

That’s a good point.

According to this comment, he needs to get a grip.

They both handled this badly.

The couple probably should’ve said thank you, but making a sarcastic comment over it was only asking for trouble.

Then the husband took it even further by turning around and making things threatening.

All of this over someone holding a door. Yikes.
