An apartment complex in Southern CA near a Marine base tried to to rip me off on my deposit. I found out other complexes were doing this. Both unethical and illegal practices, particularly preying upon the Marines that moved frequently.
I called the base liaison officer and he basically said there was nothing he could do.
The problem will fix itself well within 3yrs as PCS' occur.
Years ago (before Marine Chevrolet), a previous dealership was run out of Jacksonville for unfair practices targeting Marines. Every week the off-limits establishment list is published in the local paper.
I don't live in Jville anymore, but last I was there, many of the tobacco stores that opened were also blacklisted for selling spice and other synthetic drugs. If the establishment wanted off the list, they had to query the base and undergo inspection.
If a Marine is caught violating the order = Article 92 and punishable under the UCMJ, which is a strong incentive for compliance.
Of course the weak kneed "leadership" that was at Lejeune when I was there last caved into the Onslow County's Sheriff's office and began requiring Marines to obtain a "command letter" before getting approved for a CCW. Even though the requirement is not law, and not required of civilians.
Point being the commands can have a lot of impact on unfair practices......if they want to.
