Last time I used one was at a gas station, where I was filling up the boat (80 gallon gas tank). They wanted extra precautions for me pre-paying $250 (us dollars) on my credit card. Had to get phone approval from the card company and they ran a card imprint as well. Total headache. Sold that boat, now I have a smaller boat with a 25 gallon tank (comparable to an SUV). This while thing was about 5 years ago, maybe a couple more.
