[Vectis Hamstery]

Rescue animals can have sketchy background infor action for the reasons described. I would agree with taking someone with you. Don't feel pressured by the person to hand over money except for anything that was agreed in advance. I would definitely suggest quarantining this hamster from any other pets, especially hamsters for two weeks so you can assess her temperament and also make sure she has no infectious diseases. I usually put rescue hamsters in a smaller cage initially to gauge their response as they can be overwhelmed by going straight into a large cage and become very fearful, but I'm aware not everyone has several different sizes of spare cage!
