Honest advertising at least
I mean if it’s in Utah it’s the equivalent of 5 regular beers.
Isn’t that because Utah has weird laws about how many drinks you’re allowed to order? I seem to remember hearing that bar patrons are only allowed to get one drink at a time, so bars just started getting bigger mugs.
A lot of states have weird laws like this. Connecticut also doesn’t allow you to have more than one drink at a time (at least last I knew) so if you and your friends order a shot and a beer they pour the round of shots, wait until you’ve all finished them, then give you the beers.
