Tyrolean Vienna
1) Fill in Ticket requisition form or make booking via company website
2) drop same at friendly lady at crew service desk inside crewroom
3) depending on workload wait for Tix or get them thrown into mailbox 10m further / I don't use the service very often so nowadays ETIX is probably preferred
4) cash/credit card accepted
4) for refund send ticket somewhere and get it back with 4,5 EUR deduction per ticket if paid cash or with affiliate company issued credit card or 9 EUR else.
If based outside main base, either do it on a transit in VIE or at company HQ in INN, where there is another travel office or do it by mail.
