No, I can't take them seriously. I'm all for bringing in what the customers want (light lager), but you don't have to go with BMC. Bring in some nice German lagers or even American made ones and offer them that. I would offer them Bitburger before I put Budweiser on tap. I've even got some people hooked on Boddington's. There are better beers available.
But if they insist, they can buy cans of BMC, warm, for $20 each.
