My credit card company likes to aggressively flag transactions as fraudulent "for my protection" — even though it's really for their protection. The upshot is that purchases at my local Apple Store (which is walking distance from where I live) get flagged. I have bought many things from Apple over the years, and buy things there at least a couple times a year. So it's pretty silly for these transactions to be flagged.

The worst part is that they don't pro-actively notify me of the flagging via app notification, email, or phone call. I have to track them down and tell them the transaction was authorized. Or more likely I just get out a different credit card and use that one instead.
