Today I went to Costco in SE Gilbert, AZ and I was walking in as I have done so many other times through the entrance for customer service to get to the food court and more often than not, the line for customer service is backed up to the entrance, so I did like many times before, moved over to where people are exiting so that I can get to the food court and I was stoped by an employee. I did not get his name but he just sent me back saying that I needed to use the entrance. While I understand that, I was confused as to when the rule started since I have accessed the food court many times using that same tour. Also, I think is ridiculous for a customer to have to walk around to the entrance then down the path, then to the registers, then cross them when more often than not they are backed up with people trying to pay so that I can finally reach the food court. On top of that, the employee approached me, or more accurately, yelled at me from a distance making me feel embarrassed of doing something I have always done and never stopped nor told by any employee that I am supposed to go around using the main entrance.
