Treated like dirt

I went shopping with my husband today and while queuing ,the lady that controls the que came towards us and asked us who was paying,she told my husband to go outside ,how embarrassing to humiliate my husband like that as if he came to beg for the groceries, my husband went outside and as I waited for the next customers to finish paying ,I started putting my groceries on the till to start paying ,the cashier started attacking me and threatening to call her manager and security to kick me out ,my mask was not on my nose as I paused for a minute because I was having difficulty with breathing,a rage started within seconds and people were now looking because she was shouting,I told her that I respect her and the law and didn’t disagree with what she was saying,she continued to serve customers behind me while yelling at me ,telling me that she won’t help me ,I refused and told her that I would not allow her to talk to me like dirt ,she then apologized when I explained to her that I was breathing with difficulty then we settled the matter with apologies,I then went out of the shop with the small trolley to the door and I was told not go outside with the small trolley (that we always aware )I then had to leave my groceries in the door to go outside to fetch a bigger trolley to push out my groceries,had my husband not being kicked out like dirt ,he would have assisted to carry the grocery bags like we always do ,Pick n Pay Family Cosmo is always a nice and pleasant store to shop at because the staff is always warm and friendly,even the Management is the best ,today was just a different day totally surprising coming from then ,the cashier who assisted was Mantho ,she profusely apologized after our rage and advised that they are under pressure,which I understood,what happened today has to be addressed, nothing annoys like spoiling a good day in a store .
