Customer service comply

Hello. I write this message with a lot of pain and disappointment. I was at the Sausage Saloon at The Grove Mall on the 13th November 2021, during my lunch break I wanted to buy the Russian and Chip roll, the lady asked me which sauces I’d like I chose 3, I told her and pointed “Tomato sauce, 1000 island and Barbecue” she then pours Mustard. I tell her I didn’t ask for mustard, she then tells me she didn’t hear me, she then takes off her mask and disrespectfully tells me, I should’ve taken off my mask, and pointed at the correct. Which I did. I then tell her I don’t eat mustard, she tells me she doesn’t have money to pay for the meal I should either take the one with mustard or leave. I asked to speak to her manager, she says she’s the manager, I asked to speak to the supervisor she says she’s the supervisor, she supervises herself. I had to leave the shop and buy my lunch elsewhere. I am honestly disappointed with the service I received today.
