Did you ever notice that there are almost no middle age people in the Israeli service industry? It's mostly high school or collage age people who are only working in that job until they move on to something better. They feel like they don't really have to treat you well since they are planing on moving on soon.
Did you ever see a 45 year old FA in Elal coach? Other airlines have plenty of middle aged FA's who have been doing the job for 5, 10, 20 years and view it as a real profession.
