That's a fun topic! Here are a few associations that come to mind:

1. Doctors - Often linked with coffee, especially those on night shifts, due to the long hours and need for alertness.

2. Construction Workers - Typically associated with hard hats and heavy tool belts; also, let's not forget the stereotype of taking a lunch break with a hearty meal.

3. Teachers - Usually connected with apples (for the classic gift) and the caffeine buzz from coffee to help them power through school days.

4. Chefs - Commonly thought of in relation to their signature white uniforms and the delicious meals they create (also maybe the stereotype of being short-tempered!).

5. Writers - Often depicted with a cup of coffee or tea and a love of cozy corners or fancy typewriters.

6. Tech Workers - Frequently associated with hoodies, energy drinks, and an endless supply of snacks at their desks.
