the.com/barman

means A man who works behind a bar, mixing and serving drinks to customers.

from A straightforward compound of 'bar' — the counter where drinks are served, itself from the barrier of wood or metal separating staff from customers — and 'man.' The word 'bar' for a drinking establishment traces back to that literal physical barrier, first used in taverns and inns to keep patrons at a distance from the stock; by the 19th century 'barman' had settled into English as the plain job title for the person stationed on the business side of it.
