No havent been to docs, dont think they would know what it represents anyway. Most people dont at the moment anyway. I tend to show it when I want to. I usually get guys asking me in pubs/clubs what it means. I tell them its the Queen of Spades and to look it up, their faces are a picture when they find out! Good conversation starter.
My closest friend has seen it and knows why I have it, she thinks its great.
Didnt know about the Vietnam thing, hope I dont bump into any Vietnamese asylum seekers! X
