Mom & Pop -- Milk and Biscuits and Quite Possibly, a New Deal on Tap????

This undated photo is from the John Holly Williams "old school" collection at the local library.  Although everything appears to be from the 1920s or even earlier, to my eye the picture directly behind the man looks a lot like a presidential photo of FDR, who took office in 1933.  The Vories Biscuit company, as seen in the tin behind the lady in the plaid shirt, was located in New Orleans, and dates back a lot further than FDR.  The crepe paper bell would indicate it is close to Christmas, but other than that, it's hard to even guess what and where this eatery might have been?  My gut is suggesting it could be associated with the logging industry, given the appearance and ample use of yellow pine, but I've been wrong before.

All suggestions and even speculation welcome!

Others have suggested that the photo is of Herbert Hoover, which, given the Depression Era during his watch, actually ticks more of the boxes. 

I just read an ad from a 1915 newspaper that guaranteed that the milk was "sanitary," which was apparently "code" that tuberculosis would be warded off, as a result.
