So, is Payseur the guy who owned the rail lines that hauled Rockefeller's barrels of crude oil in?
French aristocracy, the France Rothschilds who had the palace more grand than anything the French royalty could cobble together. Goes without saying. Yep.
Figured The Payseurs bankrolled Rockefeller for a "certain" percentage of the business. Then provided acces to furthering the development of sales and partnerships. The silent partner as it were.
Thought it was manners, etiquette related. Pleases and Thankyous. Elbows off the table, sit up straight. Heard it as a kid, not from parents, but somewheres else.
