AITAH for tipping 83¢?

I went out to dinner with my wife last night. When the bill came I gave the waitress my card. She came back shortly after looking upset. She slapped the card down on the table and said “declined.” I thought her tone and brevity was rude. I took out a different card from my wallet and handed it to her. While I was putting the first card in my wallet she didn’t move.

I looked at her and said “You okay?”

She said “If I go back and try to run this are you still going to be sitting here when I get back?”

I asked her if she thought her tone was appropriate for speaking to customers. She said “you’re only a customer if you pay.” I asked to speak to her manager.

She left with the card. My wife said maybe the waitress had encountered scammers before and was anxious about it. I said being rude and being cautious are two different things. The waitress returned with my card and the slip to fill out. She said “This one worked. I’m sorry.”

I thanked her and took the booklet. Our bill was $91.17. I wrote in 83¢ as the tip and $92 as the total. I handed it back to her and started to get up to leave. She said “you’re really not going to tip me?”

I said “no, you were rude to me.”

She said “I have to tip out the bartender and the busboy. I just paid money to serve you.”

I said “Well, in the future you shouldn’t be so rude.”

My wife thinks I was an AH to the waitress and should have given her ten bucks at least, because it was an honest misunderstanding. I would have given her $28.83 if she wasn’t rude to me, but I don’t want to pay to be insulted. Was I the asshole?

For the record I called my bank and the card was flagged for fraud because of a pending $1 change that is often associated with fraud attempts. I resolved it.
