BOISE, Idaho -

A handful of Idaho hockey fans are suing a Boise arena, saying they were duped into thinking a $7 beer contains more brew than a $4 beer.
    
The lawsuit says the home arena of the Idaho Steelheads hockey team defrauded customers by charging $3 more for a tall, narrow cup advertised as a "large" that actually holds the same amount of beer as the shorter, wider cup described as a "small."
    
Four fans filed the suit Tuesday in Boise's 4th District Court against Block 22 LLC, which does business as CenturyLink Arena.
    
Brady Peck, Michele Bonds and William and Brittany Graham are seeking $10,000 in damages.
    
Arena spokesman Mike Campbell said he hadn't yet seen the lawsuit and can't comment.
