I did this once about 15 years ago in Nakhon Si Thammarat. I said to my (ex) GF and her family, "OK guys, you enter the park and have a nice time, I will stay outside and wait for you." Which I did! Of course, the family could not understand, as they all thought I was a Rockefeller member. I could easily afford the entrance fee, but for me, it's all about the principle!
