Seems like a fine line. At $3, you don't really expect more than a chair and some autoshop coffee. However once you cross that line where you're paying similar prices to a movie maybe $7 an hour you start to expect more.
And maybe include "how many pence to a pound"? My assumption is this is like pennies and the US dollar - 100 pennies to a dollar; therefore 100 pence to a pound?
