Panera Bread has been doing this. I often use them.
Have not been to a Panera since they went full left wing bat bleep crazy and told customers that their legal open carry or CCW were not welcome in their units.
I suspect that the local ones here in GreenAcres (a full open carry state) may tone that down, but decided that they were not getting another dollar from me...and have not been back. Used to spend alot of $ there.
