Yea, me too........ Here in God's country I open carry. Just saw a retina surgeon in Longmont, CO (north of Denver). Nothing on the new patient paperwork and nobody said a word (receptionist, tech, nurse & doctor); just another day in paradise.
My optometrist is extremely friendly (not a personal friend), I always OC there, has made me glasses with reading Rx on the bottom and shooting Rx on the top at no extra charge. I ended up not liking them as the main Rx in the center was too narrow/small. He redid the lenses for a very small fee w/o the top Rx and progressives at the bottom.
OTOH - My cardiologist was on my friendly list. ODd there regularly for a number of years and had many good conversations.
Then the doctors who owned the building sold the real estate to the hospital across the street. I presume a business decision recommended by their bean counters as they stayed at the same address as tenants. The hospital has a hard GFZ rule which now extends to this building.
The doctor/surgeon is too good to lose and knows my history too well to make a change at this point, so now I OC an empty holster there. The nurses and rest of the staff all smile - they understand my message. Not my favorite solution, but in this case, it works for me.
