"第一個乘客叫杯面會比全體空姐沮咒" <-- the first pax who orders cup noodles will be collectively cursed by all the FAs.
The FA then proceed to describe how they'll try and reduce the smell e.g. by cooking using multiple changes of water.

I've been told cup noodles are only stocked for US and UK flights.
I've also been told by someone else he had the unfortunate distinction of being the first bxstard to order a noodle, and set off a chain reaction throughout his cabin.
