During high school I worked at McDonald's. One of the strategies we were taught was to up-sell. Always suggest another item for the customer to buy. "Would you like a fresh apple pie with that?" or "Would you like to add an order of fries?" became the byline. I don't know why but it really bothered me to try to push a product when the customer already had the menu before him or her. I passive/aggressively refused. One day, the one manager I actually liked had reminded me to up-sell for the third time and I managed, again, to "forget." "Next time you don't suggest another product, I'm going to write you up," he warned me. Oh, no. I'd be written up at my dead end job as a McDonald's robot. However would I go one in life? The threat was still useless. Since that time, I have found that up-sells are common but they bug me just the same. I can read. If I wanted a fresh apple pie, I would have ordered one. Better yet, I would no...
