Suppose there were a podiatry practice named Pes Integer Sit. How would you put this into a complete sentence?
Do you simply treat it as indeclinable? For example, would "I am going to Pes Integer Sit" be Eo Pes Integer Sit, or Ad Pes Integer Sit eo?
Similarly for a business whose name is a noun phrase in an oblique case. If the business were named Pedibus Sanis, would you have to avoid declining it, when, say, it was in a place in a sentence that called for the accusative or nominative case?
And if these are indeclinable, does that cause confusion?
If there is a custom for choosing the case of business names, please let me know. That might (happily) render the whole question moot.
