If we're talking bottleneck jobs, opticians is definitely one of them. They're needed pretty much everywhere. Ace & Tate too is looking for young opticians. How do you target those specific youths?
Oi mate, how many fingers, still? There's always someone asking these questions to your drunk friend. Next time, however, the optometry students' guild will pull out one of these beer coasters instead. When one's sober: they function as an accurate Snellen chart. However when a person had one too many lagers – all of the sudden hands get 7 or more fingers. Time for some new glasses, buddy.
The idea is to make the students feel like they're their friends' opticians for a moment, in a fun way. Start working for Ace & Tate and you will perpetuate this feeling.
