Enterprise Inns is hoping to profit from the trend in the United States for selling customers measures of pure oxygen for the price of a pint.

The company's Oxygen Bar in Leamington Spa is the first of its pubs to offer oxygen, which can revitalise a flagging customer.

Donna Burnett, the general manager of Oxygen Bar, said: "The craze of oxygen bars across the States and the Far East, where some bars go as far as offering strawberry-flavoured shots, hasn't yet peaked in the UK."
