Cash America Pawn review: Gun safety

Visited the store a little while ago and everything was good except I heard some arguing and looked up and a lady standing at the guns with long grey hair was ranting about something. I then heard another woman say take your medicine you're being a [censored]. I really hope Cash America mentally evaluates their staff that's around guns all day. If she's mentally ill she shouldn't be around guns at all. This is a time ticking news bulletin any day. I felt very uncomfortable and decided to get out of there before I end up as a casualty... the woman was clearly still mad about something when I left. I think all stores that have guns needs mental evaluations. I won't be going back which sucks because they had a few electronics I was looking to buy but went to another pawn shop and got what I was looking for. What's your mental evaluation policy is on these people? News stations should make a story about mental evaluations on gun shops including pawn shops! Is this how all your stores are? What IS your policy on gun sellers?
