So embarrassing

Yesterday I finely got a chance to take my car to the shop for an oil change. When I got there the guy asked me if I had at least an hour to wait for it to be done. And my reply was " that is about all the time I have to get it done. Just an hour, please do not let it go over I have to be somewhere. He says no problem not over 1hour just sign here and wait in the room. He was really cool.
So I sat in the waiting area . There was only guys in the room, so before I started reading my book, I said hello and some small talk and then that was it; they carried on with whatever conversation they were having.
After 20 minutes the Tech comes in the room and said "Miss, your almost didn't have any oil in you car. We only had about 2 oz taken out. That is not good miss. When was the last time you had the oil changed?
Me: Uhhh, I can't remember.( have a very sad face) and the Tech says " well you are suppose to do it every 3000 miles or 3 months whichever comes 1st"
Me: I know, I know it's just that that uhhhh I don't know. The Tech goes " this is bad"
Me: I am sorry? I just didn't have time that's all. Then he said well just make sure to keep track this time. I am saying this because this is very bad for your car. Me "thank you very much. I will pay attention this time"
After he left, I looked around every body was staring at me. I go: I know I am suppose to get the oil changed. But I just lost track of time. Every body started giving me advice on how I should really be careful not to do it again. That I may get stranded on a deserted road without help. I just listened and said thank you.
But Gosh, I was so embarrassed its not even funny. I was thinking on what they might think of me. You know, that I probably don't have the common sense how to take care of my car. Which they are probably right judging by this incident.
Any ways I couldn't not wait to get out there. While lounging today I remembered the whole thing, and just started laughing. I really wanted to choke that Tech though for making me feel stupid.

But then I know that I deserved it. So....
