I feel weird if I can't see the entrance. If I'm working then I need to have a view of my vehicle as well to keep an eye on my equipment. My wife knows these particulars and always attempts to set me up since, "he needs to sit here 'cause he's a lefty and will elbow everybody!)
I also like to sit with my strong side inside if in a booth. I feel less exposed for some reason if I needed to get to my pistol without much attention.
