Specialist Burton

So, called to get my windshield repaired and they addressed me as "Specialist Burton". I asked why and they said because they are affiliated with other companies I do business with, they knew my former rank was Specialist, so, as a mark of respect, their policy is to address current and former service members by the last rank they held. I understand their sentiment, however I disagree. I am not now a Specialist, nor do I want anyone to imply that I am due the respect one should hold for members of our current military, persons who have been deployed in combat. What do you think? I mean, if you are a former servicemember, how would you feel on this subject?
