The only problem is, how many folks actually carry those cards? I fear a majority of average gun owners are going to continue eating where they or their family wants, despite a no-gun sign.
Of course that just means the rest of us have to step up our game and pick up the slack. In other words, don't just give the manager/owner a card one time and never go back. That may be the only one they ever see. If you make it a point to post every place on the local gun forum, and everyone inundates the business with a card on a regular basis, it will make them see that their bottom line just may be affected after all. Just please, remember to represent us well by dressing neatly and being extremely polite with your interaction.
