3) You can have your face done!
4) *Very important!!!! - Go somewhere that is busy and is recommended as I went to a new shop that a husband and wife owned. When I had mine done, the woman locked the door and the husband went into a back room while I was havign it done. It wasn't until I was dressing after did I notice that they had put the closed sign on the door and I also caught a glimps of the back room, when I got my coat and noticed they had CCTV of the room I was havign my spary tan!
Very scary - it has now closed and I think they had a few complaints!
