Solve staffing issues and giving hard of hearing the opportunity of front of house hospitality.
Our corporate office café has introduced sign language screens showing staff how to place our coffee order in sign language. This was introduced when the café recruited a range of new staff members, many who are hard of hearing.
My favourite order is cappuccino which has a movement reminiscent to Peter Allen with the maracas.
