customary

“At half-past nine on this Saturday evening, the parlour of the Salutation Inn, High Holborn, contained most of its customary visitors.[…]In former days every tavern of repute kept such a room for its own select circle, a club, or society, of habitués, who met every evening, for a pipe and a cheerful glass.”

“When two people met for the first time in Diaspar—or even for the hundredth—it was customary to spend an hour or so in an exchange or courtesies before getting down to business, if any.”

“customary tenants”

“The tenants are chiefly customary and heriotable.”
