- JYJamie YorkJul 8, 20241.0Super rude. All I wanted was a half a cup of ice. They wanted to charge me over $3. When I questioned it I was told (in a very nasty voice) “it is posted!!!” I didn’t notice their faded sign - but that still didn’t warrant the rudeness. I promptly said I didn’t want it then and she snatched it and stomped away… I know this is a tourist town with thousands through a day, but that still doesn’t mean customer service is out the window.
