#also the little sound effect when Michael and Uriel grance at each other - can it be bc they feel that they can't come in yet?

Throughout this whole sequence the angels can't come into the bookshop until Aziraphale specifically invites them.

"Shall we discuss it inside?"

"By all means."

They still stand outside.

"Would you like to come in?"

They go inside.

The bookshop was already shared between Aziraphale and Crowley by then. It's theirs. The abode of an angel and a demon.
