Restaurante de burritos | Lugares en Scarborough, Canadá

I ordered nachos with extra cheese, in each little container, she only adds 2 pumps of cheese (which doesn't even fill the little container half way). Then, they shake it to make it look like there is more in the container. When I went to order another one, I asked her to fill it completely, she said "we only do 2 pumps, otherwise we run out". Why is that my problem? When I told her I'm paid her for extra last time, she said she doesn't want to argue with me and walked away and filled it a little more this time. But it's shameful to be so stingy with proportions and to have rude customer service.
