Jeez, of all the things to bitch about, this is pretty low on the list...
It doesn't bother me that someone with three months of service is leaving San Antonio and getting to board ahead of the boatload of retirees who did 20+ years any more than it does someone in uniform going to the head of the line during one of my rare visits to the commissary. Those perks were offered to us when we were in uniform, and it was our choice whether to use them or not.
Nor do the free tags bother me, and you see a ton of them here in "Military City USA" (as S.A. likes to proclaim itself). If the state wants to offer free tags to certain individuals, that's their decision. At least the recipients did something to earn the perk, unlike many other government benefits.
However, I will agree on the overhead bin issue. I am getting sick and tired of being told I need to stuff my small backback under the seat in front of me because some buffoon who is bringing half of what they own onto the plane needs to stick their obviously over-the-limit sized roller bag into it because they also need to jam their backpack under their seat. Tough shit, if the airline isn't going to enforce their own rules I am not going to reduce the meager legroom I am already getting because someone can't check their shit like the rest of us!
When people thank me for my service, I just smile and thank them back. They are trying to be nice and I sure as hell am not going to piss in their Wheaties for it. Only a complete jackass would do so. Such gestures are getting less and less common in our society these days, so if someone feels compelled to show a little appreciate towards a servicemember than I for one will be grateful to them.
Cheers! M2
