Waiters at resorts scam?

I wouldn't call it a scam when they are upfront about the money, just some enterprising men looking to show you a good time for a nice dinner and drinks? Many Canadian and American men here have relationship's "of convenience" with local women, maybe helping out with a bill or going out for nice dinners. I expect people will respond calling it exploitation or prostitution but I personally know many couples here in that situation where they are very happy and there is no reason why women can't as well. Btw I am happily married for 17 years to a beautiful Mexican lady.
