Reminds me of those sales people that stand by the exit at COSTCO. You're trying to leave and they stand in front of your cart trying to sale you a new roof or window frames.
This reminds me of a short stint I had at RadioShack years ago. I can't control a natural urge to actually be helpful, and never could get that "up-sale" thing right. That's why it was a short stint. It was good for me though; the small electronic parts and adapters section was at the back of a narrow and long store with the cash register in the front, so I got a lot of exercise walking and lost weight. That came in handy for my next job as a night watchman... but that's another story.
