From the searches I have been doing and checking combos on GAK, it seems that for search term traffic, After gets more hits.
People tend to type in what they generally want first then the locations eg. Hospitals Sth Sydney, Hotels West Melbourne, Restaurants Lygon St and so on. Ussually general to specific (but not always).
I kind of attribute it to social mentality...in realworld sense you go to the shop to get a litre of milk, but when you get there you decide you want a particular brand and it has to be full cream. You dont say I'm going to get a litre of fullcream Farmdale...you say I'm getting Milk...the specifics come after.

The reverse would be probably true if you were looking for a specific business, say'The Melbourne MotorInn' where people would most likely type in 'Melbourne MotorInn'.
Thats my view.
