A comprehensive digital cataloging system that keeps track of its customers' car maintenance history, oil-change needs, and past fuel-filter replacements puts Karl's Lube & Go's computerized record- keeping an estimated six years ahead of the medical industry's, sources confirmed Friday. 'We figured that a basic database would help us with everything from scheduling regular appointments to predicting future lubrication requirements,' said the proprietor of the local oil-change shop, Karl Lemke, who has no special logistical or programming skills, and who described his organizational methods, which are far more advanced than those of any hospital emergency room, as 'basic, common-sense stuff.' 'We can even contact your insurance provider for you to see if you're covered and for how much, which means we can get to work on what's wrong without bothering you about it. The system not only saves me hundreds of thousands of dollars per year, but it saves my customers a bundle, too.' Lemke added that he also routinely and politely inquires about his customers' health and well-being, which puts him roughly 145 years ahead of the medical industry.
