The measure was introduced in the House last week, MLive.com reported. It would ban what barflies refer to as "cheater glasses" with thick bottoms so they look like they hold a pint but actually take a few ounces less.
State Rep. Jim Irwin, a Democrat from the college town of Ann Arbor, said the state regulates meat and other foodstuffs to make sure buyers get what they pay for. Irwin introduced a similar law in 2011 after being shorted on a pint of beer and is a co-sponsor of the new legislation.
"Similarly when people buy a pint and they're served less than a pint, it strikes me as sort of low-level fraud," Irwin said.
But Scott Ellis, executive director of the Michigan Licensed Beverage Association, said he does not believe most people who drink in bars see a pint as an exact amount.
"We have other pressing issues right now that need to be addressed over the amount of alcohol in the pint," he said.
