Irish Pub economy

The Irish Pub economy is almost entirely fuelled by the Irish Pub economy.

The theory goes as follows;

• everywhere in the known universe there are Irish Pubs[1][2][3][4][5].
• all Irish Pubs employ lots of part time and full time bar staff
• at any given time, the majority but not all of the customers of Irish pubs are actually employees of other Irish Pubs, enjoying a night out
• as long as each Irish Pub gives sufficient time off for its employees to spend their wages at other Irish Pubs, the whole economy is self supporting

This theory is, of course, a load of blocks which does nothing to get around the fact that point one; everywhere in the known universe there are Irish Pubs, is true.
