Cubans

So i was i cubana pietermaritzburg last night, so i got my bill and it had extra items on it . I sent it back with the waitress so she could void all the items i did not have. I then decided to follow her into the restaurant to pay my bill where i was then asaulted by the staff. I really don't think this is an appropriate way to treat patrons especially when you are trying to settle a bill.
