I spoke to a staff at a restaurant. She was at the counter preparing the waffle.
TKL: How do you make the waffle?
Staff: I get the prepared waffle mix, add butter and egg, put the material into this waffle pan and heat it for 5 minutes. Then it will be ready.
TKL: Are you working here full time?
Staff: I am a part time staff. I study Hospitality course in Nanyang Poly and work here during the weekends.
This is a useful and practical skill. Maybe, she can manage a restaurant one day. Or start a bakery business.
