What is your biggest pet peeve?

My dog who wants "to go" where she wants "to go" and not in the trained (or so I thought) and out of the way spot. I hate those unexpected "sticky bombs"!

Most of hate/despise/can't tolerate/would rather watch a chick flick then stand in line at the grocery store. My personal philosophy on "self checkout" is that I am performing the duties of someone who gets paid to do this and I pay the same price for the groceries regardless - f--k that - but I digress. You're behind one of those "super couponers". 10 minutes and half an order and you're still waiting. Then the person finds a price discrepancy or argues over an expired coupon. While you can feel the cob webs growing a manager finally comes over to enter the magic code or turn the magic key...

Undisciplined soldiers, or service members in general, is my biggest pet peeve. I think that discipline is the foundation of our military. But going in line with what you are talking about 1SG (Join to see), it would have to be wearing their pants bloused too low.

Ignorance

My biggest pet peeve was office pogees trying to get me to do push ups for an undone button after I got back from Vietnam.

My latest: you're driving on a one lane road and the driver of the oncoming vehicle is way over the center line and lead-footing it. Not knowing if the driver is going to move, you steer your car so far over to the right, you're off the pavement and the butthead waits till the last second to swerve on to their side of the road. This is especially annoying on a curving road with a lot of trees. My neighborhood and town is like this and I encounter these types of drivers daily. How I wish my second car was an up-armored HMMWV so I could "right back at ya" to these Alpha Hotels :-)

its a toss up of out of shape soldiers or soldiers who dont possess the warrior mentality i think we've seen our fair share of both these examples

1SG (Join to see) I agree completely, and would also add to that: all ill-fitting uniforms. I worked in men's clothing for six years before enlisting in the Navy and one of the things that is absolutely true is that the ill-fit of clothes is often what make them look bad; read an article in GQ or Esquire and time and again, the simplest and most consistent advice regarding fashion is to have your clothes properly fitted. (Obviously, the fashion trend of ultra-tight fits for men is a bridge too far, but the point about proper fit still stands.)

A lot of Sailors are simply wearing the wrong size in their NWUs and NSUs, and often the complaint that I hear is, "I like to be comfortable." That is ridiculous: Properly fitted clothes are comfortable and tend to last longer because high-traffic seams are not stressed more than they need to be due to the poor fit.

My biggest pet peeve is: ANYONE WHO RETURNS AMMO! Never did it. Wouldn't know how to do it. Unless you have nothing but expert B4 (sniper) qualified troops in your unit, you just made the list!

Some O in another part of the country has to set an arbitrary date for sleeves up or down as if personal comfort should not be in the equation. Same rocket scientist that determines when the heat and air come on in a building regardless of the outside temp. How smart do we look when we are inside with sleeves down with the heat on or sleeves up and an ambient temp that of Carslbad Caverns? Other than that...every meal a feast, every day a holiday.
Yeah, petty crap, but it has always been a pet peeve. You asked.
