Working short orders is all about timing. It's important to be able to finish some plates right in time while starting others. So you'll have to multitask. And be careful with wet stuff in deep-frier.
Lucky you, having fresh walleye all the time. We get frozen fillets mostly here.
Have you checked that thread out yet?
