Administration personnel behavior around altar

Before mass, on Saturday evening mass for the "Sunday Mass" of Palm Sunday, during the setting up of the altar, one individual woman who is a person who either volunteers or works in the adminsitration of the parish, regularly walks around barefoot (in socks without shoes), and walked around the altar is this fashion while setting up the altar for mass. I am unsure if this is problematic in any way according to Canon Law, Catechism and encyclicals, but seems like the Pastor should be setting standards of conduct that isn't, say "strange" like this. This was eye witnessed by the site owner.
