MR Tham Kok Cheong and 10 other members fear they cannot play badminton every weekend at the Safra Toa Payoh clubhouse.
The club's multi-purpose hall might be closed for two weekends each month, from October till February next year.
During this time, if there are takers for the space, vendors can hold warehouse sales for items like cosmetics and videos.
Safra, a social recreation club for national servicemen and their families, also has clubhouses in Mount Faber, Tampines, Yishun, Toa Payoh and Jurong. Members pay a yearly fee of $40 or $60.
Safra Toa Payoh reserves the right to ensure that no more than two weekends every month are booked for events. If there are no takers, the venue will revert to badminton use.
Notice is given to members two months before the dates.
However, Mr Tham and his friends are unhappy that the hall in Toa Payoh has been block-booked from October to next February.
Said the 55-year-old trainer: 'Why have they booked it all the way till next year? These sales promoters are using Safra premises to promote their products. They are depriving members of the use of Safra facilities.'
Lieutenant-Colonel (NS) Ho Lye Sum, chairman of the executive committee of Safra Toa Payoh, said the multi-purpose hall is the only available venue for holding events such as competitions, carnivals and fairs.
The rental collected goes towards the maintenance of the multi-purpose hall and club facilities.
