Trying to use my zender card downstairs for dinner...

Trying to use my zender card downstairs for dinner instead of upstairs I have always done it this way but for some reason today they told me after I had gotten my order that I had to have only chicken so I went upstairs customer service cuz they wouldn't give me my discount for my birthday in the customer service lady said too bad I got the wrong kind of chicken so she just basically told me to get lost thanks a bunch
