Stupid McDonald's sanitizer policy

Yesterday (25/07/2020), I went to McDonald's Dobsonville. Welcomed by "Phila" not sure if it's his real name or what (He is 1.6m + in height, wearing black and gold Adidas sneakers). This guy saw me using my hand sanitizer and tells me that he is still going to sanitise my hands because he doesn't trust what's in mine. I told him that I also do not trust what is in his and went out. My mom approached him and spoke to him, this guy claims it's the policy, what I fail to understand is why does this only apply to him, it was not my first time going to that McDonald's and use my own, even at Ghandi Square I am allowed to use mine. Can I find out if we not allowed to use our own sanitizers at the stores or if it's his own stupid policy
