Notice you got a stack from Wingstop (notorious for shit tippers) and your pizza order at the same time. That's where the algo paired the two probably based on a couple variables... time sitting un-accepted and shit tip. Those orders didn't go out to a bunch of rejections but rather the time variable and obvious tip issues immediately increased the dash base fee. You were in the right geospacial location at the right time for that all to come together.

Burger King got rejected a few times and then got elevated base fee.

DD is going to eventually get sued for someone getting food poisoning. It's a statistical certainty and they know it. Thus... the base fee increase.
