Can you please speak proper English?

I always think that if you want to be in the service sector, your language has to meet the mark.

Hence if you decide you want to join an airlines and be a cabin crew, please for the love of god, know that there is no such thing as stuffS.
"Please ensure all your stuffS is secured in the overhead compartment."
It's stuff. Stuff is PLURAL. There is no need for a "S" after it.

And if you ask the FO to take a picture for you and you think it's not very clear, you don't say "Why brur brur wan?"
L is pronounced as L, it does not mean, just because you are chinese, you can automatically replace the pronunciation of the alphabet with a "R".

And for the love of all things kind and fluffy, if its a motor vehicle, it's not necessarily a motorBIKE/motorCYCLE. A motor vehicle is a vehicle with a motor. It's really not that hard.
