Someone who wants to buy a Klein bottle from me can go to my website, buy a bottle, and come down to my office. I print out a receipt and a packing slip, and then send it out. I’m excited to meet whoever buys a Klein bottle from me, and I make sure that when they see me, I hope they will be my friend. My robot delivers a box of bottles, and I bring it over to weigh it. I take a picture of it, and then go outside to take a picture of the customer against the sky or whatever is blossoming. After that, I wrap up the package with bubble wrap and sheets of unimportant information, a calibration decal, and runs from 0.0 milliliters to zero hundred to zero thousand milliliters. I guarantee the Klein bottles; if it arrives broken, I’ll replace it immediately. I also have a little forklift robot to pick Klein bottles from stock.
