Just because they’re nice on screen doesn’t mean they’re nice in person. That’s the lesson Twitter has learned after running into a celebrity in person and being terribly let down.

Leading in the nice category? None other than Harry Potter star, Daniel Radcliffe.

“Dan stood outside in NYC on a cold January [sic] night and signed every last thing put in front of him and took a selfie with every last person who wanted one,” @WeActuallyDidIt recalled of histime meeting Radcliffe.

Yet, not every star was given such raving reviews. RuPaul, who was apparently less-than-thrilled to receive a passing compliment from a few of his fans, and Wendy Williams are two names who were called out multiple times in the thread.

You know what they say, don’t meet your idols, and if you happen to be so lucky, don’t take it personally when they’re a dickhead.
