I think I know which cache you are referencing, but when I did it the cache container was loaded with quarters.  
I've been to quite a few caches where an entrance fee was required.  Usually these are state parks.  What about the virtuals in the National Parks?  One of the most educational and enjoyable caches we did was a virtual in a National Park.  What about the G-O BOB cache? Are those to be considered commercial caches?
I'm sure there are other examples, but we always have the option to not do a particular cache.
