I have made the equivalent of three days' takings in 24 hours," he said. On the road outside, water has risen to a depth of 3ft but locals and sightseers have kept him busy. Mr Dean, 58, added: "I have never known business like it".
With his raised lounge bar remaining dry and the promise of staying open all hours, he offered beer and sympathy to many who have been forced from their homes.
Glen Tiswell has been forced to close one of his restaurants in Gloucester because of the water shortage and the opening of the second has been marked with the arrival of portable toilets.
Mr Tanswell said it was not the grand opening he had in mind for The Grill, a restaurant and bar, and said it was vital that water supplies were switched on as soon as possible.
He has already been forced to close Bearlands, his other eaterie, and his cheese shop, Gloucester's Finest, until the water is back on, which could take up to two weeks.
He said: "It has cost me £20,000 to set up The Grill. If the water is not back within two weeks, I will be bankrupt."
Peggy Cross has only been evacuated from her home once before - during the Blitz. The 86-year-old was rescued from her sheltered accommodation in Abingdon on Sunday morning and has spent three days in the Holiday Inn, which is acting as a rescue centre for 100 evacuees.
Peggy is a resident of Cygnet Court, a sheltered block which was built on stilts to protect it from the neighbouring river. She woke up on Sunday to frightening scenes. "It was ominous," she said. "When I drew back my curtains and saw all the water, it was shocking - three or four foot deep and gushing underneath the building.
"The only other time I was evacuated was during the war, from London to Harrogate during the Blitz.
