Sounds like you learned your lesson...stop beating yourself up. We all have times when we are not as sharp as we would like.

I tried the pocket carry thing for awhile... when seated it is a big problem to gain access quickly. I carry OWB only at 3:30... no matter if seated in a restaurant or in my truck I have ready access to my EDC.

This incident ended with no one being hurt..... that is a win.
