Rude assistant at pep store in Reitz.

There’s a rude lady at pep in Reitz who always asks people how old they are. I have to always pop out an ID or my drivers licence each time I go to the store because of my height. I wanted to know at what age do they allow a person to enter the store and they should write a notice on their door that specifies that we must come with our ID’s to the store.
