Imagine the horror of living in some country that has to deal with two or more languages. It's just not CIVILIZED.
Except in Finland where 10% of the population are native Swedish speakers so all the road signs are in both Finnish and Swedish. And in Canada where a huge chunk speak French.
How about those weird countries where they DON'T SPEAK ENGLISH but they get enough Americans as visitors that most of the signs are also in English? Like they see a "need" for a big chunk of the people using a service and they ADAPT meaning that YOU, the non-Spanish speaker can easily simply IGNORE IT.
Grow up. You live in a big world. If this is the worst it gets for you then be thankful.
