An older man in a light green shirt and dark green pants holds the hand of an older woman as they pass an outside eatery with teal umbrellas.
An older looking couple is glancing through a glass window of a busy restaurant.
A man and woman are not assumed to be a couple.  Passing by an eatery does not imply that they are glancing through a glass window.  An eatery is not assumed to be a busy restaurant.
The man and woman may not be couple, and the restaurant may not be busy
A man and woman together does not always imply a couple. Passing an eatery does not always imply a glass window. Eateries are not always busy.
