Evil Employees Are Evil
Customer complaints do not have a trickle up effect. Getting mad at a cashier doesn’t initiate a ripple effect in which your complaints are delivered through the ranks until every CEO of (fast food chain) has heard your voice. Most customer complaints directed to lower level employees will usually just be made fun of in the crew room.
to be completely true to all aspects of ordering food, make a comic about a character that is too shy to talk to the cashier, who whispers their order and is told to repeat themselves like five times before just leaving the restaurant in tears
And then the ones in drive through who whisper their orders, are appalled that they’re asked to speak up, and then scream the order so loud that it does hearing damage to the order taker.
You sound like you’re repeating an anecdote, not describing a theoretical scenario :p
