Wait staff in the United States are legally allowed to be paid below the Federally mandated minimum wage. The custom is to tip wait staff 10-15% to make up the difference. Even with tips they are unlikely to be financially solvent.
It is even worse in Wyoming as patrons resent the practice and are poor tippers. Restaurants have closed because they could not keep wait staff.
There is a riddle that goes something like: "what is the difference between a Wyoming restaurant patron and a canoe?"
"A canoe is more likely to tip."
