You're right. The founder died but the family still owns it. Either way there was a noticeable change after his death, it seemed. Maybe a coincidenceI thought Discount Tire is still held by the family of Bruce T. Halle. Discount Tire, is privately held company founded by Bruce T. Halle in 1960. Are you thinking of the Tire Rack which was purchased by Discount Tire in late 2021?
Also for the OP :: Like everything in life, some days you have to deal with the "C or D Team". You don't always get the "A & B Team". You got it fixed and maybe next time you will get the "A or B Team". Now a days employers have to take people that are C and D players just to fill the labor spots. Not good for patrons, but just a reality of today's labor workforce.
