Local brands

A popular local drink is 'Thums up'. Yes this is the spelling. I should stand for functional language and I can't make strong enough a case for the 'b', but still it pains me. There are bigger misuses of language to worry about. Ok maybe the person who created the sign which reads 'XOROX' should consider why the 50,000 other signs for this micro industry are all spelled 'XEROX'. Or I'm in error and I don't even wan't to know what XOROX means.
