Liquor Control Board of Ontario [LCBO]

I went to the Elmvale LCBO (Elmvale Shopping Center, 1910 St. Laurent Blvd, Ottawa, ON K1G 1A4), I walked up to the cash to pay, there was a tall, older gentleman with glasses. The mask mandates for Ontario are now removed, so I wasn't wearing a mask. As I'm placing my items on the counter, the cashier stepped back to toward the entrance, and stared at me, menacingly. I wasn't sure what was happening, I didn't know if he was serving me, but I kept putting my item on the counter, the cashier still looking directly at me, menacingly. When I was done he finally stepped forward to serve me. I didn't say anything because I didn't know what was happening. It was really strange, it felt very creepy, I felt single out, it felt extremely disrespectful. If he was doing that because I am not wearing a mask, that is really disrespectful. Please address this issue, because I will go back, film him and sue him for discrimination, not willing to serve customer without a mask.
