Foreign language confusion

I have been fortunate to travel to many countries and still enjoy the excitement of new discoveries in foreign lands. Nothing is more indicative of a country than its way of communication through its language. It is impossible for me to learn the language of every country I visit, so a few words are picked up here and there, polite formalities and the all important word for 'toilet'.
In Vietnam there is a bombardment of signage on the streets advertising all manner of items. Some are easy to read and interpret especially when a picture or English translation is attached.

Others are just a guessing game.

And just because!
