Years ago when I worked at Taco Bell someone got fired because the manager walked in on him snorting coke off the bags of strawberry they used to put on top of the fruitista freezes in the walk-in.
Also some asshole pulled a gun in drive thru during my shift because he ordered extra cheese on his 7 layer nachos and apparently did not get adequate cheese.
A doctor died of an allergic reaction to something in her food at a Disney owned restaurant after repeatedly informing staff that she was allergic to said thing. Husband filed a wrongful death suit. Disney lawyers are trying to have the suit dismissed as he once had a trial of Disney+ for a bit and the terms of service includes an arbitration clause.
