Years ago, I went into a restaurant with my pal Bob, and as we waited a very long time for a waiter to show up, Bob said "you know, I have a secret power. I become invisible as soon as I enter a restaurant. What's more, anyone with me becomes invisible too!"
At first I believed him, but since eventually a waiter spotted us and took our orders, I think we were merely translucent.

Yes, I think this is the cannabis thread.
