This isn’t unique to indoor ranges and is a scenario which can occur at any range or location where firearm safety is neither practiced nor enforced. A range should only be open when an RSO is available. No RSO no range time. That simple IMO. Firearms are not toys and I don’t want to be around anyone treating them as such.
@William377 , my recommendation is to find a safe range to visit so you and your wife can enjoy the experience.
Thank you for sharing your experience. This is an excellent reminder to us all that safety is Paramount when handling firearms and when being around others handling them. This also serves as a great educational use case for new shooters on what to expect and what they should tolerate at the range.
