Imagine this, you work at this place pictured above. About 10 times a day you have to run down the entire "menu" for people that can't read or are too drunk to remember what they had.
There's also the "off the street" crowd that pull up to a table without looking at the bar that place their order with a waitress/waiter with the "Gimmie a draft". There was a place in Rochester, MI that looked like that place, only not as many brews offered. It was GREAT!
