I have carried concealed in that store numerous times and I believe a couple of clerks were made aware of it on a couple of occasions. It stays concealed in the holster and no one has said anything about it.
I once took it in for the express reason to have someone look at it during the warranty period. Before going in I made sure it was completely empty and had the bright orange plug in it that shows the chamber is empty.
If you look at the counter top where you check in, there is a hole in the counter top and one in the ceiling overhead. The lady behind the counter told me the counter top hole was a .22 and the guy was being a real jerk about having to unload it up to the “bang” point.

The one in the ceiling was another incident with a rifle.
Thunder gun range also charges by the gun or number of people whichever is higher. They don’t “tag” guns. The prices per gun or person is very low. You can only use targets they sell and that is how they make their money. I have put stick on paper “dots” over the holes so I could use them a second time and no one said anything.
I don’t mind the charges per target because they have spent a
lot of money improving the range
tremendously since I started shooting there.
