huspa1-7, Exercise 1: The wristband system Model answer: At entry you receive an electronic wristband or card that opens your locker or cabin and records any extras you buy, such as massage or food, which you pay for when you leave. The risk: losing the band can bring a charge or a delay in leaving, and it opens your locker, so keep it secure and on your wrist or tied to your things. Arrangements differ by bath and should be checked.
