You've created a great row of shops there, Mark, and I look forward to seeing your development plans come to completion. With all those shops, though, you'll need a fire station!
One thing that attracted me to Playmobil was the detail of the sets, particularly the little details, such as the butcher's knife and chopper (I've forgotten the proper name for it).
And hairdryer is the word you were wanting, Mark, although over here in the UK they tend to have a hood which goes over the top of the customer's head.
Of course, your 3666 can have a place in this too, as the centre piece overlooking the flourishing shopping area you're creating. You could call it the Castle Square Shopping Centre.
