I was discriminated against -- refused service and asked to leave like a criminal despite being a long time customer and having done absolutely no wrong.
I kindly advise staff be educated on proper procedures for treating mask exemptions with kindness instead of attacking potential customers and asking for personal, confidential information to be divulged. I even offered to wait for my order outside, to which I was told I couldn't be served :( The only thing cashiers at aux vivres should be doing, is taking orders and ringing them up (isn't that their job ?!), however the current attitude at aux vivres is not only ILLEGAL, but it's traumatic and hurtful... especially from a vegan restaurant that I assumed valued ethics and compassion. I will sadly never eat nor buy AV products again and advise all those who care about equality, personal rights, and mental health to do the same.
