A wet sponge in the face in the street was a price worth paying for staff at Panadero Lounge in Macclesfield.
Passers-by donated £1 to throw sponges, with one onlooker giving £20 to tip a bucket of water over victims.
The fun was in aid of East Cheshire Hospice which has received more than £4,000 from Panadero since the café bar and restaurant opened 17 months ago.
The sponge dare raised £75 in minutes to end Panadero’s latest month-long fundraising challenge.
General manager Elli Warhurst said: “The chefs and front of house staff got drenched but didn’t mind in the slightest.
“The £901 raised was one of the highest totals across our chain of Lounges, so the group kindly contributed a further £500.
“We’d like to thank customers and staff for their generous support.
“Every Lounge could nominate a charity. As GM, I chose the Hospice which is close to my heart. It was a no-brainer.
“They do an amazing job and friends and relatives have received end-of-life care there.
“I’ve done a sky dive before and know how much money the Hospice needs to operate.”
Elli also swam 179 lengths of her local pool – the equivalent of two lengths of Lake Windermere – having barely swum since she was 10.
A customer treated for cancer donated four jars of Swizzells as a prize for a guess the number of sweets competition.
Guessing the name of a cuddly toy elephant was another fundraiser for Panadero which runs monthly quiz nights.
