That is the first thing that comes to mind if you're reading a story like this, but if that's happening to you, in the heat of the moment you feel too devastated and just want to get as far away as possible from that place that made you feel like this.. (the drive-thru in this instance). Like imagine you go in there and you're unable to even say the sentence "Lemme talk to your manager". I'd need to be on some mood-boosting drugs to actually prioritise having a talk with the manager in this situation lol
