Oh, absolutly!  In a machine shop, you just might get laughed at for 
clarifying between a tenth of an inch and a tenth of a thousandth.  
The thousandth is ALWAYS assumed in a machine shop.  A tenth of inch 
is for those guys that don't know how to hold a micrometer in their 
hands ;-)

So, yes, most people, within their trades, make certain assumptions 
that is confusing to others.
