This is true for all of retail 

I trained so many people at our grocery store. No cost to the store. Just showed them around, they watched a video, check some boxes, etc. Thats it. 

You go through so many people if you are a longer term employee (perhaps 6 months to a year) if you are lucky you end up training your replacement.

I worked at a department store when I was in high school. Every time we had a new hire the boss would say “Show them the ropes.” I’d then take them to the hardware isle &amp; point out where the rope was.
