No matter what the business is,, there are stupid employees, un-educated employees, power tripping employees, & other undesirables working in places they shouldn't be. And in todays climate of "I can sit on my rear end & the government will give me money,,, vs working" attitude,, it's often a sad reflection of what employers have to work with.
Sounds like a polite, yet firm written letter to corporate with specific details may or may not get results. But at least you'll be on record complaining about the clerk.
The comment about the BB gun, and a 4473,,, is interesting. Could it be that the State has mandated a BB gun as a firearm? The 4473 is a FEDERAL form,, and it's use is governed by the federal regulations. Seems a polite but firm letter to the State Attorney General, ATF, Corporate, & any & all organizations in Ohio that fight for gun owners needs to be sent. In it,, ask WHY a private company is using the 4473 for purposes OTHER than intended, or allowed by law.
Case in point;
Many years ago, a local wally world had a sale on Ruger 10/22's. I wanted one of that model. The clerk told me I had to fill out (2) identical 4473's to complete the purchase. He said; "One goes to the ATF & one is sent to corporate." I politely asked for the manager. When one arrived, I politely inquired about this. I ALSO pointed out to the manager the PRINTED portion at the top of the form about; "Prepare in original only." And in my discussion I said for the store to send one to corporate was illegal, and de facto registration. The manager said; "It's store policy & if you want one, you must comply with store rules."
So, I politely did as asked, making sure I noted the clerk, and the managers name etc. I then filed a complaint with the AFT, Wally world corporate, and even the NRA-ILA.
That wally world STOPPED that policy.
And in a follow-up, I was able to point out how firearm THEFT was occurring at that wally world,, by employees. (My best friend was a Federal agent.) Apparently, a few employees had figured out a way to "add a firearm to a 4473" and it go out the back door.
Now,, when I fill out a 4473 at any FFL I'm not familiar with,, I mark through the empty space for any additional purchases. (That's legal BTW. ATF explained that one to me.)
So, I'd question the laws in Ohio, and if the STATE mandates the BB guns as firearms,, then there MAY be an exception for the State by the ATF for the use of the form. I'm not current on all the Ohio laws. But I am a member of the OGCA,, and haven't heard about this process by the wally world.
