As the title says but in regards to tourist type areas. If I walked into a shop in the USA and they charged me more for being from NZ I would be less than happy. But if I went to a national park and the fee was more for a foreigner I wouldn't mind as long as. 1. The extra was somewhat reasonable. 2. It's clear you are paying more. Tourism does price locals out if some areas or failing that makes certain areas a treat. I'm not a fan of tourists being scammed. For example prices have to be displayed here so if you order a steak you might expect to pay the menu price. But in some places they might charge you hundreds of dollars when you go to pay. How much extra I expect to pay varies by country. We had a tourist here get charged $25 for a whiskey which you would expect to pay more like $8 or so. The $25 wasn't a premium whiskey and in a hipster bar you might pay more. I have been caught out when ordering from wait staff and the prices are at the bar and I don't think to check the price. That's on me.
