Refused to be allowed in Chester butcheries because i prefer using my own sanitiser

On the morning of the 25th of August 2020 I went to chester butcheries on Arbee drive, Othongathi. When i arrived at the entrance the security guard took my temperature reading and proceeded to offer me sanitiser. I told him that i will use my own that i carry around on me because i once had a allergic reaction to sanitiser from another store. He then said it was the shops policy to use their own and said he will call the manager so i can explain to him. When the manager arrived i told him my story and he said that because i wont use their sanitiser instead of mine which clear states that it has 70% alcohol content, i will not be allowed to purchase from their store. I left the store without being allowed in.
