What phrase can express frustration about not having enough coffee available?

The phrase "I wish we weren't constantly running out of coffee in this flat!" clearly conveys frustration regarding the recurring lack of coffee. It highlights a specific issue: the frequency at which coffee supplies diminish, indicating a sense of annoyance or dissatisfaction with the situation.

The other options do not effectively capture the same sentiment. For instance, expressing a desire for coffee to never be present contradicts the original frustration about its lack, rendering it irrelevant in this context. The notion of wishing to find coffee suggests a more hopeful tone rather than frustration at the current situation, which also does not align with expressing dissatisfaction. Lastly, wishing for there to be "always coffee" implies a desire for abundance but does not communicate the frustration associated with the current shortages and habitual running out of coffee. Thus, the selected phrase is the most accurate representation of the feeling being expressed.
