I was about to start a thread on this, so y’all better answer!
There’s a series of ad on TV for flavoured milk. In one a guy is drinking flavoured milk while waiting in line for movie tickets with his girlfriend. He gets to the ticket window and the lady says, “that’ll be one adult and one child, then” and his girlfriend stalks off in a huff. The guy then shrugs and the slogan “Tastes good, but” comes up. This I understood and deemed very witty by TV standards. Enter next ad in series.
Guy comes out of cornershop drinking flavoured milk. He steps onto the pavement and whistles to his dog and says “c’mon boy” or something similar ( I don’t THINK it’s important). The dog sees the flavoured milk (presumably) and slinks away whimpering with it’s tail between its legs. Once more the guy shrugs, drinks the milk and the slogan “Tastes good, but” is heard. When I first saw it I thought it was something like “cats like milk not dogs” but this would be a LOT crapper than the other one so I’m thinking I missed something. WAG’s welcome!

My WAG is that the dog is ashamed to be seen with his adult owner drinking a “kid’s drink”?
