It's supposed to never leave your pocket or your hand. Besides, if someone gets your credit card number and purchases something, you can charge it back. The vendor is supporting the risk, not you.

If you buy something in a store, you have no certainty that your CC number doesn't end in the hands of store personnel.

You have to keep an eye on it. It is easy to overlook if the amount small is enough.

All in all, I wouldn't call this good security practice.
