Wearing tripple layered mouth and nose covering

I went to Usave Kleinvlei for milk and bread covering my mouth and nose with a triple layered covering. Then the security allowed me in only to throw me out because covering is not a mask I told him to check the masks of other shoppers only single or double layered whereas mine is tripple layered the third security watched from a distance then the two pulled my trolley to the front of the shop then telling me to wait for the manager then when the manager did not appear they told me to wait outside for the manager I screamed on top of my lungs for manager to come because today I stood more than an hour in the line in the hot sun I did not even seek preferential treatment as a healthcare worker then the manager came to me telling me to give my money to him and wait outside the shop for my groceries by that time I was beyond myself asked by him if he wants to tell me I must give my bank card to him I said leave me in peace to pay my shopping and rather use their energy on checking how many layers the mouth and nose covering is .i was watched carefully but allowed to pay so they can get rid of me .
