Poor staff behaviour

I visited the branch in Bellville with my son (5yrs old) and the lady at reception said nothing. While walking another walked up to me and said "no kids allowed in the gym". I just said he will be with me. I later note there were other kids in a different section of the gym but kept quiet. While I was running in a passage my son started to run as well and one of the guys at the reception desk started yelling. I immediately stopped and left the facility. I will definitely cancel my subscription ASAP and join a child friendly gym
