A lot of call centers are set up with rolls and rolls of little cubicles so crosstalk is not unusual. I can't remember if it was AA or some credit card company but a few years ago I got chatting with the agent and we discovered she was in a call center about five miles from my house. It would have been easier to meet her in the parking lot and do whatever business we were doing. On the other hand I was working with an Internet based travel agency a few years ago and during one of the conversations with my assigned agent I heard a dog barking. Asked her about it and it turned out she was working from her home in Phoenix for a Ft Lauderdale based agency.
