Really? There was a time in the City back in the late 90s or early 00s when a chap with a bottle of Bud in his hand was a very common site.
I fail to understand how anyone can claim that it's a bad lager. Fosters I get. Carling I get. Both taste pretty awful but Bud is really rather innocuous, it's just a standard, inoffensive lager.
Mind you, it is a large American corporation.
