Just a strip of chicken to a vegetarian

Not the first time the attitude is down right pathetic ... Once a week I go to this specific Mc Ds and the attitude is always rude today I went to order a egg Mc ****in and I told n. Ngcobo crew id 8 that I wanted no meat as I'm a vegetarian she said no we'll take the meat out . I'm like I usually order a Mc ****in that just has egg Nd cheese she begins to rant about me saying there's no meat on this one just a "strip of chicken" along with me ordering the correct thing then disappears and tells the manager to come speak to me ... Lovely lady btw she gave me my correct change and my egg and cheese Mc ****in sorry for not knowing the lingo but I don't want to feel like I must fight to get what I want
