Bitter, unpleasant experience at Daily Coffee Fern on republic

I had an awful experience 3 days ago, I had just experienced load-shedding and I had a deadline looming which I had about 15 minutes worth of work to complete. I literally just got my chai latte, the waiter asked me if I would like to order anything to eat and I said maybe later, and I asked him to leave the menu on my table. The manageress approached me and told me, very impolitely that I have to order something to eat and I'm not allowed to "just" have a cup of coffee and sit there the "entire day" as she needs to recover from Covid losses, I was there for 10 minutes when she came to me, my intention was to stay no longer than an hour. I didn't even have a chance to look at the menu, this took my appetite away and I had to ask her if I may finish my latte. I had my laptop out and was just about to make a call when she came to me again and asked me to move to a smaller table, I will honestly never set foot there again, I literally left after I finished my latte. I would recommend the waiters inform patrons as they enter that they not allowed to order a coffee only before they are seated.
