Not only this, but they aren't hiring the best of the best who are even smart enough to know the difference between the sidewall pressure and the tire placard pressure.Please don't anyone be mad when I say this: they probably don't pay enough for the person doing the work to care. I have worked with so many people who take no pride in their work and just point to a seemingly low pay for them to just do the absolute bare minimum or less to get by.
You rarely get what you don't pay for. And but you almost certainly never get what you do NOT pay for.
