Poor service, *****ing liberty and discriminating against clients

I was just in Makro and while there is no mandate on mask wearing in place they allowed me access but refused to put through my transaction. I was I a hurry and just wanted to leave so I took out a mask and put it over my nose and mouth. They were still not satisfied and voided my transaction. They just wasted my time and all without any reason. They are treating customers really poorly and in my opinion requesting ******* interventions.
