At the Oxford Wine Company in Witney, Oxfordshire, staff donned wellington boots so they could continue to work in a flooded shop last weekend.
Assistant manager Gautam Nagpal said: “It came up to about a foot high in the warehouse, but in true English fashion we got on with it.
“Customers still walked in and we managed to serve them. We’ve got a lot of soggy boxes and damaged labels, but we got through it.”
At Wine Rack in Tewkesbury, Gloucestershire one member of staff broke off her holiday to man the shop, because flooded roads prevented colleagues from reaching the town.
“Business would have been quite bad had it not been for her,” said assistant manager Cheryl Kavanagh. “Sunday was really busy because no-one could get out of the town so they were all visiting our shop.”
Although floodwater stopped just inches from the door of Worcestershire wine merchant Upton-upon-Severn Wines Ltd, owner Alan Goadby said the weather had nevertheless affected his business.
He said: “We have done very little trade because people are afraid to come out. It has been very frightening and unless you’re in it, it’s hard to understand what it’s like.”
This summer’s heavy rain and cold temperatures have been blamed for causing a slump in drinks sales at retailers across the country.
