The funeral of bowling stalwart Eileen Adams, 79, will be held on Wednesday July 10.
For more than 40 years she ran the centre in Friars Square, Aylesbury, with her husband, Stan, until it closed in controversial circumstances last year to be used as part of the new H&M store.
Former Jardines manager Kevin Pollard, 54, started working at the centre when he was just 15 years old.
He said: “I went straight from school to there. I wouldn’t work anywhere else. Eileen was a second mum basically. When you work with somebody for 37 years you do get to know them.
“I learned a lot from both her and Stan. They helped me in life.”
He added: “Her death is going to shock a lot of people because she was still very fit looking for her age, very active and working right the way up until Jardines closed.
“She was not just doing a nine to five job, we are talking sometimes about 12 hour shifts.”
The funeral will be held at Amersham Crematorium at 4.15pm and anyone is welcome. A decision has not yet been made on family flowers. A wake will follow the funeral at Rivets Sports and Social Club.
