It's amazing to me how many people don't realize this, and think it is somehow safer to leave the card unsigned.

Back when I worked as a cashier (at Target, of all places), I actually had people get offended when I would ask to see their ID because their credit card was unsigned. But I know many/most of my co-workers didn't check...

Also in the category of things the store should check but rarely does -- The merchant is supposed to call the credit card's issuing bank before letting someone else use the card -- this also angered people when I would tell them I had to call the bank to let them use their spouse's card.

Throughout the entire franchise, no matter the distance of the trip, the turbolift takes exactly the same length of time: the precise time needed for the passengers to complete their conversation.

Spock was by himself, so I'd say the turbolift was working exactly as designed.

Not entirely true (former Target employee speaking here). The store has an obligation to ensure that the person using the credit card is the person whose name appears on the card. Normally, that is supposed to be done by comparing the signature on the card to the signed receipt. But if the credit card isn't signed, the store has to see a picture ID. Now, I will certainly agree that a lot of stores don't do this (or don't check signatures), but this is what the stores are technically required to do. What I was told as an employee was that this prevented a customer from protesting the charge on the basis that someone else used their card. It's the same reason that cashiers are supposed to call the telephone number on the back of a CC card if the card has a spouse's name printed on it -- have to make sure the customer didn't just steal a card and claim to be the spouse.

Bad analogy. Let me modify it: DRM is more like a padlock on a homeowner's breaker box or water heater, requiring the average, unskilled person to pay an employee of the manufacturer of the device to enable him to change his house voltage from 110VAC to 40VAC, or get hot water from his own property at 99 degrees Celsius. In other words, stuff that "the average Joe" isn't really likely to do, and quite possibly not even stuff the majority of /. readers are likely to do. I really think DRM is intended to, and mostly does, deter the casual thief, just like the lock on your house. Sometimes you lock yourself out, and yes that's a pain, but no one screams "I only live in houses which aren't kept locked so as to really allow me to enter and leave freely and in the manner I choose." That would be foolish.
