My best advice to deal with tourists and English would be to read the paper, read popular magazines, watch popular entertainment television and also listen to podcasts. Are you familiar with itunes Getahun? There are lots of podcasts there to listen to and hear, some even with vocabulary.

It's a tutorial. You will find the "free" podcasts there once you download itunes in the itunes store.
Have a great week!!
