I went to the Starbucks shop inside Macys (111 N. State St. CHICAGO) to ask for a cup of water. I was very thirsty felt hot and tired after walking through the store making purchases and carrying large Macy's bags, also wearing a small back pack. I approached the Starbucks counter and asked if I could get a cup of water. The female Starbucks counter person ( female, name tag began with J) promptly told me I could not get water without a purchase. I responsed I had never heard of a Starbucks requiring a purchase before allowing a person water. In summary, another male Starbucks worker ( name tag began with a T) interviened and stated that what the other worker told me is correct. I was told Starbucks in Macys is licensed to Macys ( therefore operates per Macy's descretion as informed later by Starbucks phone customer service rep. with futher explanation ). Another worker at Starbucks ( Macy's wearing a black colored top with a small starbucks emblem ( no name tag) directed me to a food area several feet east of the Starbucks where I could go and get water. I walked over to that food area after I informed Starbucks workers I would report their refusal to give me water ( while carrying my bags of new Macys purchases, thirsty, hot, tired) While walking away from the Starbucks I looked back to see the initial two workers appearing humored with smiles and unfazed). I was able to get a small mostly iced cup of water from a worker at the food area mentioned. The water was refreshing, not enough water though, I dared not ask for more.
