Kitchen staff?
They are the waiters. I've been to weddings where I met the janitor of the local elementary school. He works in the kitchen at the school when he's not mopping, and does the same at the wedding hall. What do you think, there are Michelin star chefs in that kitchen
?
As he said
I don't know about breading shnitzel but taking chicken quarters and lining them up on cookie sheets and drizzling some sort of sauce (viznitz BP style) and shoving them into an oven shouldn't take more than 30 minutes. same for the potatoes and green beans altogether. Soup can take a little longer with cutting the veggies and all but not more than an hour. While making knishes from scratch may take a while, the pre-made ones are just a dollar a piece and it should take less than 30 minutes to line them up and put in the oven.
I think your hasagos of what's acceptable are too high to look at this objectively.
This is how they make the food...
They put a waffle chip in the mashed potatoes and somehow it look fancy.
