Why is it that so many non-chain hotels take credit card numbers by e-mail ("you can split it over two e-mails for security"). Do the credit card companies not know this?

All Amex cards start with a 3
All Visa cards with a 4
All Mastercards with a 5.

This much is a fact, with no exceptions so why does every single customer service agent ask me to declare which card I'm paying with just as I'm about to submit my account number? Eliminating this dumb question would free up zillions of man/woman hours and help the economy. Is the age of automation really as fupped duck as it appears or is there a secret reason for wasting everyone's time this way? (See also the automated request for account number while you wait for a human to come on the line and ask you again for the same information already just submitted)
