There is a saying in Ireland that two people cannot go out for one drink. The basis for that is that pub etiquette is such that if someone buys you a drink, you must return the favor. The real reason is perhaps that over 10,000 Dubliners make their money from Guinness one way or another.The St Jame’s Gate Guinness Brewery can make 2,304,000 pints in one brewing. A kind of job security that will surely be practiced in Dublin on Tuesday, happy St. Paddy’s Day.
