There are still quite a number of people who thinks that cabin crew members are "flying glorified waiters and waitresses" and we do really want to change this perception as being a cabin crew is never easy. It's not just about asking coffee or tea. It's always about safety and a small mistake can result to casualties during an emergency situation. Cabin crew aspirants go through months of intensive training and as some have even said, if they studied the way they did during cabin crew training, they would have already been valedictorians in college.
There are even some who almost drowned during the ditching drills where they have to jump into a deep pool without any life vest!
Watch this video of Emirates cabin crew going through training. It's not as easy as you think indeed.
