1: I only carry a pistol so that I never second guess myself if I have to shoot. If someone pulls a weapon on me they mean to do my harm, I will return the favor.
By carrying the pepper spray you will also cause yourself a moment of pause, as you try to decide what to reach for in a critical moment.
2: How would you be intimidating them? I don't feel like I am when I carry, but I also don't care what they think because I carry for my protection and the protection of my family. You will never be able to normalize carry if you don't carry.
3: Don't bait the cops, lol. I have only had one encounter with the police and all they wanted to know if that I had not done anything illegal, two out of the three were nice people.
4: How did they know you had a gun? Not trying to pry, but was it out in the open? Sounds like that was an uptight place to work anyway, there are jobs that allow it. Mine does, in fact they allow me to take my gun into the warehouse to keep it close if I felt better that way.
5: This is just me, but if it is not posted I would carry in there until they ask me to leave. And if you have the permit to conceal just cover it when you walk in.
Not sure if that is what you were looking for, but heh. I open carry because of one reason, safety. I have always known you can carry in Missouri but never really thought it was for me, until my family was walking and a dog came out of its house and attacked the small dog with us. No amount of kicking affected the dog, at that time I realized that if that dog had attacked one of my kids there was nothing that I could have done to stop it. My son is now scared of big dogs because of it, and both are terrified to walk down the sidewalk that the dog had come from. That is when I decided that I would carry, so that my kids would not have to be scared.
