No, it's not expected but it could be negotiated, it's also a good icebreaker for a first meeting. It's a nice gesture of encouragement to show the client is truly interested in meeting and the escort won't knock at a door and not get an answer.
I would suggest doing it late at night and if you're not close to metro/public transportation. Besides you know for sure they guy will show up and won't ghost you.
@latbear4blk for example offers to pick up guys at hotels and takes them to his place. Maybe that has something to do with a escort who post on here and refused to go there because he considered the area not safe. Anyways it's a nice way to help someone and an "indirect" way to tip him.
