I got a birthday voucher to eat at Zest restaurant...

I got a birthday voucher to eat at Zest restaurant 2 days ago but I was working all day. The voucher only valid for 1 day only. Its ridiculous. The club director or marketing manager should consider the members birthday voucher to be used in a month rather than 1 day. Most of the club in Sydney give birthday voucher for member to be used in a month except Rooty Hill RSL club. I've been a member with this club for 2 years now. Last year I used the voucher with my family and it was so bad. People queued up for an hour to get foods at Zest. I really disappointed the way of their management about member birthday voucher and I hope they will change it.
