Hi:) There are two case studies in my rubric paper and you choose one of them and write about it. (Not a two, Chose one Air Environment or Beef Mystery Guest) I need at least 4 cited references (MLA). You can find references on google and use it with good explanation and good supported writing with that sources. This is Advanced prin of Service Management class and we are handing about food** and guest** service mostly. So please write it professionally with good sources and analysis because professor is quite strict and he likes to use information from book. (Managing Quality Service in Hospitality by Ford) Not mean cite reference from here. Use the basic information when you write the essay. There is well explained description on Case study rubric what I submitted here. Please read rubric analysis for case study first then start write the essay! Thanks! Stay safe always:) I also submitted the two photos for better and easier understanding from chegg each one is for both each topic so you can consult one of them what you chose the topic. But Please Do Not Copy from their and just look up for better understand how it has to be write! Thanks you so much again.
