Vivi gives a sigh of relief when she notices that her destination is a mechanic's shop. Usually when she's meant to meet with a client, it's in some seedy bar or a brothel or something of that nature where she has to fend off amorous attention in the middle of negotiations. A respectable public place like this is much better for these types of meetings! Then the only one she might have to fend off is the client and, being her own boss, she can just tell them to shove the job where the sun don't shine if they piss her off too much. She probably won't in this case cause the money's too good, but she can.
When she gets her first look at her potential client, she registers his choice in attire and becomes slightly nervous. While businessmen usually pay well, they're also the ones who are more likely to add "extra services" to any given job. Then she has to put her boot up their ass and remind them of their place, which is usually awkward. Except for that one time that it turned out that was exactly what the guy wanted. Then it was REALLY awkward. But she's stalling. And trying to distract herself from the fact that her contact just dropped something on his foot. No need to bring that up or let on she saw that. Men and their pride after all. She looks over the younger girl and wonders if this is who she's going to be in charge of protecting. That's usually the way this works when the client brings someone else along. Still, no point in coming to false assumptions when she can clear things up right here.
"Ya'll put in for a protection service?" She asks. If they say no, then she can just carry on her day and try to find her actual clients. Otherwise, that should be a fairly tame way to tell them that their bodyguard has arrived.
