Some years ago I returned to Cancun with the cabin ceiling on fire in a 767. Customs proceeded to search be a noxious & confiscating all the duty free the crew had just bought on departure from Cancun. My intervention to point out the crew were pretty traumatised having just dealt with an emergency. Just got Mexico has rules! Tbh I would walk away if that particular customs officer was on fire. Indeed I hope she suffered some horrible future as she obviously was not human.
