You forgot the part where it charges you for the Frappe anyway because the charge is automatic (for your convenience!) and you have to figure out which customer service you need to call to reverse the charge. Spoiler: you'd have to call all of them, wait half an hour on hold on each and at the end you'd have to reverse the charge at CC company because none of them know how to deal with it. Reversing the charge would block your car account and you'd have to spend next month with Uber while it is being sorted out. And by being sorted out I mean you complain on Twitter and one of the Silicon Valley founders notices it by chance and mentions it in his feed, from where it reaches the support of your car company because their support VP reads it, and it is flagged as something to be handled by an actual human.
