absurdity witnessed: voice from within

went to the bank machine last night, couldn't figure out why there was someone at the outside one when the inside one was free. went in, pulled out my wallet, when a hand stretched down over the darkened screen from within. a voice said, Hey! i screamed and ran outside. i waited and used the outside machine but realized i needed a deposit envelope from inside. i finished up, went back inside and again - the hand and the voice. screamed again! and then i said, "just getting an evelope!" obviously it was a repair guy -- or maybe a robber! -- i didn't really stick around to find out, i will call the bank today just to be sure. the voice and the hand at that confidential moment really spooked me, i have to say. in hind sight, i should have asked more questions - after all he was pretty far away inside the machine and i am sure everything is on tape. maybe shouldn't have used the other machine. i wonder why they wouldn't lock the door when the machine was being serviced. an odd experience to be sure.
