Hi David,
A very good question and I am sure you will receive several replies.
I personally found most of the answers to my questions which were very similar to yours in The Restaurant Workers Handbook by
Jim Pace, I found it answered many of my questions and more.
I did find that I had to slightly adapt some of his thinking to the U.K. style but all in all it is a very good book filled with useful and practical comments.
Just my opinion and I hope this helps.
best regards Trevor
