Goloso Restaurant

I ordered a chicken cachapa and told the girl more than 3 times no pink sauce or mayonnaise she wrote it in the paper I came out the restaurant to eat my food in my car I started eating but I felt it tasted weird to my surprise it had pink sauce which is made with mayonnaise I am allergic to it, I told them about it the girl there was like it doesn’t have any ,I told her look into the plate she realized it had the pink mayo sauce,I told them I want my money back they were saying we will make another one ,they said I was rude by me complaining about them not following the instructions the kitchen cook came out and was like you don’t have to complaint we can just make you another one I told him it’s a big deal when some one is allergic to something.
One other thing I been here more than 10 times and never had this issue but today

Very small place.
Food is delicious.
Ordered 1 chimi de Pollo.
2 chicken cachapa.
I patongo.
1 mofogitos.
Gave her 100.
It was 45 .
She gave me back 50.
Now it was less than delivery but really? What happened to me 5? I guess that was tip?

I went there to pick up a delivery order, which they handed over through a little window on the street side.
One of the female staff was so rude, she talked to me so aggressively.
She didn't even let me look at the name on the package that she kept inside the premises - just saying aggressively to confirm the order.
 Even though I talked to her in English, she talked to me in Spanish.
I know there might be biases between people and different races.
But training staff to show respect to all customers and providers would be awesome.
