Here we are at IMM, where there're lots of these kiddy ride machines. As with all kids, Isaac loves to sit in them. We don't insert the coins in them coz we don't want him to get used to it and ask for coins to be inserted all the time.
In this way, he can sit in them for a long time, and still enjoy them, and yet, it doesn't cost us any money. Nope, I don't think we're stingy or anything - we feel it's a matter of discipline.
I mean, look at him. He's so happy! He can happily sit in it for a good 10 minutes at least, being happy all of that 10 minutes, and happily saying bye to it, and hopping off to another kiddy ride and be entertained by that too.
Trade this for 1 minute of happiness in a gyrating machine with awful loud music, lots of whining, screaming and crying for the next 15 minutes after that in a bid to get us to insert more coins... nah.
