Being a flight attendant is a service industry. If you don't want to serve and interact with people, then work as a taxidermist.
The passenger asked for a blanket. There is no need to be bitchy, condescending , mocking about it...the type of behaviour that is found in primary school. playgrounds.
The tone was nasty, and those who said those mocking words assumed that they were superior in the English language, except they couldn't string a sentence together grammatically, and was semi broken English.
If you are an air steward, you are supposed to be well travelled, tolerant. Passenger wants a blanket, give a blanket. What is the problem ? No need to mouth off about it. I am sure that there are many really nice pleasant airline crew , but tainted by these three. How many other passengers did they mock and treat badly ?
