[That...is not a normal reaction for people coming across him for the first time. Crowley watches the guy's expression with unmasked confusion, brow furrowed over his ever-present sunglasses. Until, of course, he got a little too much into his personal space bubble, and addressed him by name.

...Well, that's obnoxious. [That way of saying his name. Ugh. Was that a thing somewhere? ] Either you've met me before, or my reputation has preceded me. Could be either way, really. Given your tone, I'd put my money on the former.

[That and the whole purring and getting into his personal space thing. That's a big hint. ]
