Bathroom etiquette

Is it just me or is it wrong to carry on a conversation on your cell phone while in the stall in the bathroom? And doesn't everyone know to wash their hands after using the facilities by now? I experienced each of these atrocities in one trip to the bathroom today.

When someone is on the phone, I make an effort to flush an extra toilet or two for emphasis (hoping that the embarrassment will come from the person on the other end of the phone as opposed to me confronting the one in the bathroom). And to see someone leave without washing their hands is like seeing someone smoking nowadays. Both filthy habits -- not good for you or the ones around you. Come on people!
