indian and arab passengers
Really not a problem - one person tried to accuse you of being racist and the other went into a wierd planet of X equals Y??
End of the day - there is no Arab or Indian passenger - lots of varieties in both those categories. As long as you have the ability to realise they are all human beings with maybe diverse needs and the ability to pick up on what these are not a problem!
Just get on in life and show a bit of interest and you are 50% there for any job. Words of wisdom from person who has been there and done it!!
