O'Reilly Auto Parts review: Trouble with my military discount

On dec. 30, 2:00 pm, an older employee questions my eligibility for my military discount again, even after decades of being a regular patron of O'Reillys and submitting my dd-214 military discharge paper previously on multiple occasions. He demands a military I D card which was never issued to me (I served 1975 thru 1978), all I have is the dd-214, sufficient proof of my service. This store is located on North ave. in villa park, illinois.
