A 50% tip can get your credit card flagged as potentially fraudulent activity.
Wouldn't they just see the total?
I've had transactions flagged for (intentionally) leaving large tips before. These large tips were justified for various reasons, such as comped meals.
Could be the specific credit card company I use?
What makes you think it was flagged for a large tip specifically, rather than just an unusually high transaction?
It still confused me how they would know it was a $20 steak and $80 tip versus 5x $20 steaks and no tip. It would appear the same, a $100 transaction at Bob's Steakhouse.
The message specifically said it was due to the "unusually large tip". They wanted me to confirm that it was intended.
If the article linked below is to be believed, the credit card company does indeed know how much of the transaction is a tip due to the way the transaction is processed. Note that this was at a full-service restaurant, not tipping at the counter for fast food or some other thing.
Consider when you pay with a credit card at a sit-down restaurant, they read the card first. Then you write in the tip on the receipt, meaning that they process this part later after the initial card reading. It is probably different with the tabletop self-checkout devices though.
