Here is a conversation from a fiction:
'What brought you to Sydney, Mr. Piron? Business?
'"Frenchies" --fashion boutiques that I'm opening in Sydney and Melbourne. I'm manufacturing here from French designs. The openings and first showings are next month. Perhaps you would like to come?'
'Perhaps.' So you bought your way in with an employment deal and plenty of money.
(the italic is what the speaker has in her mind. )
What does this sentence mean?
What are you asking exactly?
To buy your way in: Is to pay, to gain access. However without reading the book we don't know what he has bought in to.
