If you allow anyone anywhere in public (and not just in a bank) see you flash a concealed weapon, you might cause panic, leading to who knows what. If you can master the concealed part of concealed carry, the carry part should be no problem. Spend the energy you are spending now worrying about failure to conceal on successfully concealing your EDC and live your life with peace of mind. I know when you first start carrying, you can feel like your weapon stands out like that big zit on your nose on prom night, but with practice and more experiencing carrying in public, your insecurity, self consciousness and fears will diminish.
