Do it at home!

The subways and JR invest considerable money in educating the public on correct train manners.  The slogan on the posters below. 家でやろう　 is 'Please do it at home', it could also be translated as 'Let's do it at home'.  Hmmm... I don't think I will philosophise too deeply about this, but it's curious that being drunk to the point of passing out in the door way of a train, or vomiting in the carriage are considered comparable with putting on make up.  Either is fine, just do it at home, not in public!

NO!!!! don't do it at home either!!
