Problem: As a fast food restaurant, we have many issues that need to be fixed. The most significant issue is about Food portions. Seven out of ten customers said our food was tiny, like a kid's meal. The second issue is overpricing. The average price of our express food is above $20 per person. The third one is Customer service, guests are complaining about our services being horrible.
As a manager, what can I do to fix these three issues?
