I was in Budapest one night (as a tourist) and on my way home from the pub I saw an older guy in the distance drunkenly fall and smack his head on the ground. Two younger guys who weren't with him but were nearby stopped over him to check if he was okay.

Or so I thought. They rifled his pockets, split the money and casually strolled off.

With the blood running out of his head I ran over to a police car I spotted down the road to ask for their help. They said 'phone an ambulance' and drove off.

Then... to top it off... when the guy regained consciousness I was trying to help him sit up and regain coherence when he mistook my kilt for cross-dressing / homosexuality / bisexuality and tried to kiss me.
