Inquiry Submission By MortUSA_Polska

I have read that costs are often listed in US dollars. Can someone please tell me, do you exchange your dollars for Cambodian currency? If so, where? Is the exchange rate fair or a rip-off? Also to those who have traveled there did you use US Dollars? Say your meal was listed as 6USD and you gave them a 10USD, did they give you 4USD in return? Do the Cambodian restaurants, stores, deal in USD and give you USD in return? This has been confusing me and would appreciate an answer.

Thank You in Advance.
