Aggressive?

We had a customer come into the store to return a bearded dragon because it was being aggressive.

Which... O_o I've never really known those to be aggressive. Like Bearded Dragons are one of the more mellow pets to own.
Yet apparently this bearded dragon kept biting when handled. 

….Again. Weird.
Bearded Dragons rarely, if never, bite. Especially the baby ones. *shakes head*

So I was curious when they brought the Bearded Dragon back in, how it would react.

Yet. 
There was nothing out of the ordinary. 
The bearded dragon was acting pretty normal.
A bit more energetic than expected.
But it didn't try to bite me or anything. 
Mostly the bearded dragon just wanted to get out and run around. 

Soo...
Once the customers were gone. 
I put the bearded dragon back on the floor.
As it seemed healthy enough.
