If you ask him, he will probably tell you that if one expects raises, promotions and good bonuses controlling costs are very important to the chains. Draft Buds are much higher margin (or lower cost) then most high-end beers and drinks. To an 'empty suit' in a corporate office your costs are lower and you look better selling the Buds.

Of course, this logic is flawed: this is no way to build and grow sales. In addition, this logic rewards selling a high margin drink rather than a lower margin but more expensive drink where the bar makes more $ on the expensive drink.
