What are your WTF experiences since getting into the hobby?

I remember back when GW encouraged and engaged with people sitting in the store for hours, playing games and actively painting etc

Me and my friend were playing a pretty intense tactical slug out of a game in Games Workshop.

About 2 hours in I felt something gently caress my ankle from under the gaming table which was covered in material to hide store stock and cupboards.

When I looked down some guy, probably about 19 years old (older than me at the time) was peering up at me with the creepiest smile and said in literal Ralph from the Simpsons voice “I’m a Tyranid” made a gesture with his teeth (and spit) and returned to back under the table.

We had been stood at this table gaming for 2 hours. He had not “snuck under there” he’d been there the entire time. We didn’t know him.
