Many years ago, when even smartphones were relatively rare, I learned that AT&T was offering a little USB dongle that would give your computer internet access via their cell phone network for a monthly fee. I thought it was a fantastic idea and I wanted exactly that, so I went in to buy one.

I asked the lady how much data per month was included. She said it was unlimited. I said that it's definitely not. I just want to know what the limit is. We want back and forth a little bit, and after a while I just asked to see the written agreement, dug through it a little bit, and found the part where it said that I was limited to 5 gigabytes of internet per month. I pointed it out to her, reiterating that 5 gigs is fine, I just had wanted to know what the limit was.

She said, "Oh that's what comes with the unlimited plan." She argued that no human being would realistically use 5 gigabytes in a single month, so the plan was unlimited.

I gave up and just bought the thing and left, but it was such a frustrating interaction that it still comes to mind almost 20 years later when someone says "AT&T" and "bullshit" in the same sentence.
