Circle K

I was told that I needed to pay .99+tax for ice in my own container. Where in America is that right? Then to have (jae) an employee of Circle k to butt into the conversation that I was having with (lata) the cashier with her comments is unprofessional. You will charge me for ice but all of the landscaper that comes in and use the microwave and bathroom that purchase nothing is free. I don't understand how that is ok. It is hot outside for me as well as for them. It is totally unfair to me and then to get an attitude from another employee. I purchased gas and food is my money not good enough for your store?
