Red Rocks was beautiful. However, today as my 12 yr old son and I entered the gift shop, a girl addressed my son and told him to put his mask on to enter. She should've asked if he has a breathing condition that is affected by mask wearing, which he does. After we walked out, family members still in the store overheard the gift shop girl talking about us to another employee. It was very unprofessional.
