Starbucks Starbucks charges 50 cents for a cup of ice!!!! irvine, California

I've been going to this specific Starbuck shop for years, I work across the street and today was the first time I was asked to pay 50 cents for a cup of ice. So bad for business seeing as I religious go there everyday. I told the representative with the thick hispanic accent that I come here all the time and have never been charged for such a small request. She said that they charge for the cup, she stated that the company doesn't like to waist the cups of just ice. I told her that I have come this morning for a hot coffee and now in the afternoon I wanted the cup of ice to pour my coffee that once again I bought there that morning. She still refused and so I told that I would no longer be coming here. She laughed at me and turned me away. Upset, I went to the front desk of the Marriot, seeing as the shop is located inside, and asked if they were allowed to charge for a cup of ice. She advised me that starbucks is not allowed to charge anything for a request so small but only to the marriot customers. So  here I am writting this review. It's not that I dont have 50 cents, I get paid very well. Its the principle of the matter.
