Livery business
From HistoryWiki
A "livery vehicle" remains a legal term of art in the U.S. for a vehicle for hire, such as a taxicab or chauffered limousine, but excluding a rented vehicle driven by the renter. In some jurisdictions a "livery vehicle" covers vehicles that carry up to seven passengers, but not more, thus including a jitney but excluding an omnibus or motorcoach. This usage stems from the hackney cabs or coaches that could be provided by a livery stable.
