As I walk around my house trying various holsters… I wondered how I would react and feel if I was ever in a retail establishment or another place and the manager came up to me and asked me to leave because I was printing or someone saw my firearm. I mean obviously I wouldn’t enter if there was a sign posted but what if I didn’t see it.  This scenario is very probable. How would you react?

Will not happen.  A lot of us have non-resident permits from other states and have spent years carrying whenever we aren't at home.  Nobody will ever notice that you're carrying unless you're making it really obvious.  Lots of stuff can make a bump in your clothing.

The first time you do it, you're sure everyone knows.  One out of 20 adults in the US has a carry permit.  Every time you're out of state, you're surrounded by people carrying guns.  I bet you never noticed either.
