Great Advice

So I got an iced mocha from Caribou Coffee today and just loved the cup, especially the bit about learning to say thank you in ten different languages. Feeling inspired by the cup I did, so here goes:
Spanish- gracias
Italian- grazie
French- merci
German- danke
Chinese (Mandarin)- xie xie
Arabic- shukran
Japanese- arigato
Dutch- dank u vel
Hawaiian- mahalo
Portuguese- obrigado

Now I did get some of these off the Internet so if they're wrong please correct me!!
