I have little doubt that bartenders at the local VFW bar would be able to quickly spot depression and PTSD type symptoms among veterans. But there’s a couple shortcomings here. First, not a hell of a lot of young vets go the the VFW. And secondly, it’s a long way from noticing that a customer is showing symptoms to actually suggesting to the customer they need to get mental health care.
Plus, it’s not just VFW bartenders. I’d be willing to wager a heck of a lot of bartenders could spot the symptoms in their regular customers.
