Be careful with this though. Never bring a requested item to a first time session. If it's a sting operation and the undercover has asked you to bring her something (a drink, condoms, snacks, etc) it is considered an act of further agreement and can add an additional charge to your arrest. It also makes it impossible to turn and walk away at the last moment. If you're holding the bottle of diet sprite she requested, it's hard to say you were just a stranger passing by and not the guy who has been texting her.
