Only if they're un-trained monkeys. Anybody who has any experience can tell if a tire has been run too low long enough to cause damage, & knows the warning signs, AND knows to dismount & inspect the interior of the casing. They can easily tell this to any employee they hire that understands the language used to hire them, but they don't. Incompetent help, lack of competent or any training, even just experienced oversight of a newbie, all missing a majority of the time anymore. They can train 'em how to take Your $$$, that's about it. Doing things right, training competent help, is just too much bother for everything from a corner tire shop to a Cadillac dealership. There's no money in it to help somebody, then compound that with risk. They're just not into it, buy a tire, or good luck if You don't have a functional spare.
