Mobile phone usage in toilets

One of the funny things here in Singapore is that people are talking on the phone while they are at the toilet in office buildings. It is funny entering a fancy building’s toilet and hearing hard core business conversations from the “toilet cubicles”. It happens 7 out of 10 times I enter an office toilet (regardless of company or building).

I find it hilarious, just imagine a conversation:

"Dan: - Then should we do that million dollar deal lah? Can or cannot lah?

Sound of flush of the toilet in the nearby toilet cubicle….

Scott: -Ah…. sorry ah… just flushed your offer down on the toilet…. Please give me a better deal ma… one million cannot. Only half million can!"

Can’t imagine what one thinks when hears toilet flushing over the phone at the other end of the line in a serious business conversation…..

Is this a practice in other countries as well? Or only Singaporeans are that funny to think that only their voice can be heard over the phone and not the other toilet noises? Please share your experience if any :)
