Chipotle Mexican Grill

I have been to several Chipotle in Cincinnati, OH and when I ask for extra meat and I know that cost extra and willing to pay for it. But then they want to give me half potion of each meat that I paying extra for. Maybe if I received a complete potion I wouldn't have to paid for extra meat.
Then they always don't have something Evendale store yesterday. No cheese, no Vinaigrette no Guacamole. Last month they didn't have lids to get my sour cream on the side.
This very frustrating after long day at work.
