Irritating encounter with staff in subway

Hi, just using an anon account as I don't want to link this to my main. So I am still buzzing after an encounter in Subway yesterday that has left me wondering whether to contact management or take it to social media.

When I entered I asked the staff member if they still do the vegan meatballs to which he replied, quite smarmily, in the negative. From the off I was getting bad vibes from this guy like some sort of reverse snobbery towards vegetarians but anyway I asked for the vegan patty. When the time came for the salads he said just lettuce I suppose and I said no i don't want lettuce (i never get lettuce) but I wanted peppers, onions, jalapeños, black olives, pickles, and maybe a few other things. Now at this stage he rolled his eyes very plainly and made a big show of adding these ingredients to my sandwhich, then I asked for a combination of three sauces as I always do with no problem, but at this stage he is behaving very rudely and starts to complain that I am not wearing a mask to which I told him there is no sign on the door making it clear that masks are required. We got into quite a heated exchange about masks where I told him he should be wearing goggles to stop transmission through eyes and how often were they cleaning the surface tops actually and that he really should be wearing a hair net if he cares so much. To make a long story short he shouted at me to leave (this had nothing to do with the mask as he was obnoxious towards me from the start) without serving my sandwhich. Still fuming as I write this.
