Confirmation is worthless without cash in hand. She might have a case in court to cover the cost of supplies, but that’s a lot of time away from your shop hoping to make the money back. Again, Tesla is a bunch of asshats for doing this, but there is a very real chance that the person in Tesla setting this up has no idea how long it takes to prep and make an order like this, and may have thought they gave enough heads up to cancel. Twice a month I get people asking to come to my restaurant with 80 people and all order individually. I tell them no, that’s not how large groups work, I can’t accommodate 80 individual orders at the same time along with the rest of the business on the floor. I have never had a person say, “Oh, that makes sense.” Every single one tries to fight back and order separately. If you don’t work in the business, there is a very strong chance you have no idea what is happening behind the scenes. The business owner REALLY should have gotten cash up front, and if Tesla told them no, then you tell Tesla to get their pies elsewhere.
