Advert for the Kennington Cross Coffee House
Medium: Print on paper
Coffee first came to Europe through the port of Venice, and the first coffee houses opened in England in the 1650s. Coffee houses came to be called 'Penny Universities' because a cup of coffee cost just one penny and customers could stay as long as they wanted talking to friends and colleagues, or reading the free newspapers. Signs reading "To Insure Prompt Service" hung next to cups on counters in these coffee houses. This is the origin of the word 'tip', meaning gratuity paid to service staff in excess of the cost of goods.
