Today in Stupid Assumptions Engineers (or Designers, or somebody) Make: that people have two phone numbers.
I ordered something the other day, and paid for it with PayPal. I use PayPal a lot, and am generally happy with it. (Yes, yes -- it's not perfect. Seriously, I used to work on check-fraud detection software: I can assure you that PayPal is a paragon compared to the traditional banking system.)
But I noticed on my receipt from the company that the phone number attached to my order is downright antique. Not just old -- like, seven-years-dead, my phone number from my old house.
So I went to remove it, since at this point we've cut the cable and are just using our mobiles. And what do I find? PayPal doesn't allow you to have fewer than two phone numbers. Like, it is literally impossible to remove the dead number without adding another one.
I'm not quite sure what they expect me to do here. I'm not enthused about adding Kate's mobile onto my account. And what do they expect people who really do just have one phone to do? That's not exactly unusual.
So: Boo to PayPal for bad design.
