The sushi place here I visit regulary in vegas (nagoya trop+fort apache) are very friendly towards it. The owner lady tells me she feels safer with me there (I usually go really late before closing) and all the chefs ask me about how to carry and shoot. They are neat people....reminds me I haven't been in a long time, need to go pick up some there soon!
Many sushi places here are owned and run by korean and japanese families and its a completely different culture. For many of them, I was their first experience with seeing guns at all. Many conversations over the years with this place, and they love how approachable I've been about it, and it's been mutually beneficial.
