Answering 'The' Call

I was in the restroom at a restaurant the other night, when I heard a cellphone ring. I started to wonder who this bloke was who carried his cellphone inside the loo...and actually answered it :-O How on earth can someone talk on the phone while taking care of their "business"? Answering both the nature and telephone call at the same time is so weird. Just imagine the reaction of the person on the other end of the line if he/she realizes it! Yuck! If it were me at the other end, I would be completely grossed out and would disconnect the call immediately. Now, don't tell me that there aren't any chances of the person on the other end of the line realizing it. If a cellphone can transmit voices, it can very well transmit other sounds too, duh! Thank God, that a cell phone cannot transmit smells!
