Let me ask you this. Which would make you more upset: A business saying “We’re sorry but we can’t take any more orders at this time,” when you called in presumably weeks (or at least days,) ahead of time, or after having put in an order weeks or at least days ahead of time, getting a phone call the day before valentines day- the same day you were getting something special for the loved one; and that business saying “We’re sorry but we have to cancel your order.”>
I’ll give you a hint. one lets you place an order elsewhere, the other means your getting your pie or cookie or whatever from the grocery store’s pre-baked section.
Chances are the customers that are upset were likely to be repeat customers where it’s very dubious that Tesla will place another order there again. she may have in fact lost returning customers with that; or, at the very least provide something to make up for it, a discount for next time, or something.
Edit to clarify: a good way of dealing with being booked up is to offer them first dibs on reservations for another day. sure, they can’t take care of them on valentines, but Easter is right around the corner. it gets them to feel special; and a lot of times, even if they decline a different order, they’ll remember the effort and come back. the other response… not so much.
