[The Dark Knight Rises] What exactly was Bruce's plan if Alfred had gone straight to reading his paper without clocking the other patrons?

This is mostly for fun, honestly, but I thought it was a funny question to ask.

At the end of TDKR we see Bruce fulfilling Alfred's fantasy of seeing him at a cafe (in I think Europe?) and telling Alfred that he's OK.

Let's say Alfred's feeling a bit sad because his adopted child died and isn't really paying attention to his surroundings, does Bruce start making an escalating series of bird calls until Alfred notices?

BONUS POINTS: When, while living as a criminal in Asia, did Bruce learn to fly aircraft?
