Since my gringo passcedula is almost filled up, on my last trip I thought that I should have my nongringo passcedula stamped...POP immigration guy was most friendly but he casually asked me for a propina...I was like....why not, I keep paying propinas to everyone when I am here, but I asked him, ain't U worried, there're cameras everywhere....he smiled...non te preocupes amigo...then I asked him why I was never asked for a propina when I entered with the gringo passcedula and he said that they cannot asked for it since the gringos do not understand the concept of propina
Just an experience...
