It would make sense for restaurants to spend all their energy focused on providing delicious food, but to the customer, it is more than that. The service, environment, and staff all play an important role in the overall experience.
This is what I found at my favorite fast food place. While the food was good as always, their lack of attention to cleanliness caused me to wonder what the kitchen was like and whether their inattention spilled over to there.
You’re making an impression with all of it — the signs, parking, packaging, attire, and yes, even the trash. Pay attention to more than just (your equivalent of) the food.
