I've had concealed carry for about 20 years and take great care to not print.
My standard: I must be able to drink from a fountain, get something out of a shopping cart, or sit on a stool without someone "looking" at me noticing anything, no printing.
That's my standard ^ regardless of the legality of printing.
Strive to always carry the gun you would carry on the "bad" side of town.
My carry philosophy is "Something is worth doing is worth doing right" not "Something is better than nothing".
