There's not even an invitation to rescind, here.

Oh hey Winston! Um, who are you? It frankly looks like you're on the run from the law. Word of advice: don't expect strangers to let you in their apartment when you come randomly a knockin'. What is it about this apartment that 1. attracts randoms and 2. makes them think they're invited inside? Go away, douche. Go away, creeper. Who the hell are you and why did you decide to just walk in here? I'd like to rescind your non-existent invitation. I'm greatly confused by your presence. This presence I speak of is a creepy, over-looming fear that the feds are going to show up any minute to arrest you for god knows what. Did you not see me in the room next door when we asked you to leave #305? Why are you, five minutes later, knocking on #306 blatantly asking if you can come inside and "sit down"? Clearly, you're not welcome. It's kind of an engraved rule of thumb from childhood not to talk to strangers, let alone allow them to enter your humble abode. Please leave, Winston. And never come back.
