coffee-housing

   cheating at cards

   Referring to the behaviour of whist players in 18th-century London coffee houses:

    Coffee-housing... can range from the lifting of an eyebrow to the deliberate banging down of a card on the table. (Clay, 1998)

   The 1874 Slang Dictionary gives coffee-shop as a 'watercloset, or house of office', presumably because, as today, passers-by used their lavatories.
