At the end of the Month, the facility from staff to allow you discount without your Card will be removed. The button will be taken away, so its important you start and use your card. If you still need to collect your Card, please do so.
So far the system is going really well for us. Remember you can always add funds to your Card, then you only need to hand over your card when buying drinks at the Bar. Staff will always print you a statement at any point if you need to check your balance.
