Are you kidding? No way! The girls who send flirty replies back to clients most likely have templates on their phone for this. In the same way they've got a template message with the door number and other information sent immediately before you meet. Alongside that one there are the "I can't wait to meet you, big boy" type messages as well. Maybe she'll just replace a couple of the words (e.g the client's name, name of outfit, role play scenario name, etc), this is to make it appear more personal but of course it is not.
