THEME:   four C's in random phrases; hence the clever title 
"Foresees"   GOOD ONES:     Private beds?   COTS [Army privates]   
Brief reply?   ANS      
BTW:   Ma-___ store   AND PA [it's Mom and Pop shop; this is a non-rhyming corruption of the idiom]      
Call-to-action response to one's own rhetorical question   I SAY NO [seems the speaker is calling for inaction]      
No more guesses, just tell me   I'LL BITE ["I'll bite" suggests the speaker wants to make no guesses but just be given the answer]       
Inside company   INTEL [seems to need quotation marks around "Inside" since that's part of the slogan]      
neun, Drei, OTRA, and ACA are foreign words we don't ever use      
Diamond thieves' undoings?   TAGS [I would like this baseball one, but 
most tags occur 
after the slider is safe]      
Despite all my carping, there was much to like about this puzzle.   
RATING:    
 
Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
