they just treat me normally when oc'ing, and i oc in kroger and walmart. i only conceal when traveling out of state or its convenient to wear a coat(like last winter).Keep your head down. Maintain a low profile. That's why I carry concealed. The people at Publix and Wal-Mart aren't going to kick you out if you're carrying concealed and you aren't printing. But walk into most of the stores where you do the majority of your shopping, and see how long it takes before you're asked/forced to leave.
apparently i don't look too threatening in any form
