Brazil is a wonderful country, but I loathe these laws. People just being able to walk up and push in front of you, even after you have been waiting in line for ages.
Ugh, you will often see parents with "kids" that are 13+ pull this. When someone questions it, the parent has a child-like tantrum about the embarrassment that some poor attendant has just imparted on them. Meanwhile, junior is taking a break from his iPad to watch and will probably grow up to be just as rude.
The sense of entitlement and self-importance is over the top.
