Ordering "A Beer"

[tonypaladino]

On TV all the time you hear people sit at the bar and ask for "a beer". This is ludacris, as myself, and anyone I've ever seen in bars, clubs, restaurants, etc orders "a newcastle" "a corona" "a bud light" and so forth.

However, in casinos, when playing poker, I often notice a player just ask for "a beer". I know of no other setting where people ask for "a beer" without specifiying a brand.

Does anyone else notice this?
