I was up on the mountains in Colorado and stopped to eat. paid with credit card and did not give email but later received receipt. hate that. wasn't asked. took me a minute to think how they did that. the credit card company has my email of course! and yes, big brother knows everything.
Bank told me the debit card can't be hacked in way to empty my account. now if i lost my paper checks, that is another matter. no wonder checks are on their way out. I still use them a bit for bills.
