Random bits from a NRA member, military veteran & gun owner...
Here are a few bits I'd add to this forum topic;
Keep the gun shop & property clean & tidy. I'm annoyed by local military surplus stores & small business gun shops that are dank, dirty, dingy pits.
Have ample security, CCTVs, lights, fences, alarms, etc. It may deter crime and more importantly may help protect your employees/customers in a violent crime.
Have ample free parking or customer parking in a clear, safe, organized space. Some of the smaller gun shops & FFL holders have jacked-up parking lots next to bars, pool halls, strip clubs, etc. A seedy or run-down area may have cheap rent but it could cause major problems later on too.
Train & prepare all of your clerks & staff. Walt Disney drove this point home with his theme parks & "cast members". All of them were drilled on all aspects of the business or were able to properly assist a guest(customer).
Good service & proper business conduct seem to be less & less common.
Don't hire "mall ninjas", "weekend Rambos" or "gun shop Rangers".
A tier-one spec ops veteran or type-A bodybuilder may look good on paper but if they are unable or unwilling to be polite & professional or can't avoid any bias or spite towards some models, companies or brands then don't hire them!
I've met more than a few "hard-chargers" & "head-cases" that clearly did not have the right mindset or conduct to be in a gun shop or outdoor store with piles of guns & ammunition.
I may think of a few other suggestions later.

ps; A clever way to ID any threats or possible robbers is to post a few bikini girl/hot women posters/logo items right by a color CCTV camera.
These guys will look directly into the lense as they look at the poster.
The gag was in the 1979 comedy film; Hot Stuff,
