I don't know,
why do people want to jump into the big fryers straight away, guys and gals do an apprenticeship.
Why not learn to fry on small fryers, then take a course on how to teach people to fry with the small frying machines, that way you can gain experience, perhaps working up to teaching on the twin fryers, controlling two burgers at a time. Once you can do that McDoonals will be snapping your hand off and willing to pay you to flip and turn.
You know it makes sense!!!
