Sorry, can they (customers) demand it back?
I mean, once Starbucks have it, then the customers get it back via product (that has a margin included), or just leave it forever (free money!)
I have a firm "No vouchers" rule because of this, the vouchers in my part of the world inexplicably "expire" if not used within a certain amount of time, cannot be redeemed for cash, and will not be honoured if the business goes belly up
According the laws here they have to. Doesn't mean they won't make it difficult. And it needs to be in a separate account and business (to avoid it being drawn into a bankruptcy). Not that this has ever stopped businesses from abusing it anyway. I doubt this voucher option is available in the Dutch app because of this but I didn't bother to check.
