You really need to get in the habit of checking tires (to name one of a number of things) now and then rather than rely on a parking guy to point this out to you. Tires should never be allowed to get to the point where they are bald.
Right front tires don’t wear out faster than any of the others unless there’s a problem. That problem could be driving the beejeezus out of FWD vehicles or the alignment is off due to age/wear or something bent due to a collision, curb strike, et.
