I greeted an employee in the seating area on arrival and he ignored me. I then placed my order at the front with a female staff member and waited.
When my order was ready, a younger male staff member plopped it on the counter and disappeared wordlessly to the back while I thanked him. I then saw that the receipt said there were olives on the pizza, which I didn't order. Checked the pizza and indeed they were on it.
The female staff member was at the front having a personal conversation on the phone in Mandarin and the other employees had run off. I had clearly checked my receipt and pizza and then I attempted to get her attention and she ignored me and carried on with her call like I wasn't there. I gave up and left.
The staff were all, without exception, extremely rude, and it was quite annoying picking all the olives off my pizza.
