Lying in order to see Art: Specifically Van Gogh

So I work in a museum.
The Seattle Art Museum.
I love it.
My co-workers are awesome.
My bosses (plural) are also pretty nifty.
Previously, SAM wasn't exactly what I would call...um, world-class.
But currently we have an exhibit visiting from the Kroller-Muller Museum in the Netherlands: "Van Gogh to Mondrian." We are one of only two museums in the U.S. who get this exhibit, the other being the High Museum in Atlanta. Kroller-Muller (sorry for the lack of relevant punctuation) is a museum created from the private collection of Helene Kroller-Muller, who had the largest private collection of Vincent Van Gogh's work in the entire world. Apparently she managed to get upwards of 80+ of his drawings at one time. Cool stuff. And the main reason I am working here, as Van Gogh is my favoritest. I've travelled far to see his work: Boston, Los Angeles, Paris...Lots of other people are very excited to actually have something of this magnitude in Seattle. Which is fine. However, here at the membership desk, I am running into a lot of people who will seemingly say ANYTHING in order to try and get in for free. Is this because they are poor, and the prices ($15) are too high, and they really just want to appreciate art? Or is it because they don't care that they are LYING, and would do the same thing in order to see ANYTHING for free?! AUGH! I really shouldn't even attempt to go into the bullshit that I am submitted to. Let's just say that I know our admissions/membership policy up and down. And the people who try to give me a line are usually our very own museum members! Who are already getting in free! And somehow they think that anybody they happen to be associated with ALSO gets in free. And my thought is, we need people to buy memberships and tickets in order to keep the museum going. That is why these people bought these memberships in the first place. Do they really want to deny the museum much needed revenue?! I don't understand the evil intentions of the public. It really chaps my hide. I would never even conceive of doing this type of thing myself.
