beer question

I'm about to crack open a forty-ouncer of Colt .45 (yeah that's right, the 
truly topknotch stuff), and I remembered a friend telling me that almost
all 
beer is delivered warm to the stores, quickstops, etc. He said there's no 
reason for them to spend the money keeping it cold throughout the whole 
journey from the breweries, that it's only when it's about to be sold that

they coll it down. Is hat true?
