That's all true. You may have missed the significance of the slogan "Improvise". The man and woman have taken the dog for a walk. Dogs are not allowed on the beach, but they didn't bring a leash. So, they had to improvise.
Men who drink this beer not only know how to improvise, but they are smart enough to do it to their own advantage. (Naturally, you have to assume that this was the man's idea).
