Spitting in the Customer's Food

If you're an Unsatisfiable Customer or otherwise not Nice to the Waiter, this is how he may get back at you. It's not just limited to spit, either... as Real Life incidents have testified to over the years, an especially vindictive server may adulterate a customer's food with other bodily secretions -- or worse, any inedible or possibly poisonous substances he may find handy. And sometimes it happens not to get back at a particular customer, but at any or all customers, For the Lulz or even For the Evulz.

Finding out this has happened may prompt an I Ate What? response from the diner in question.

While Real Life incidents are not explicitly excluded from this trope, please keep in mind the Rule of Cautious Editing Judgment, because some cases start at Squick and get much, much worse. Also, do not list examples of food adulteration born only of greed or depraved indifference -- this trope is explicitly about contaminating served food as a kind of revenge, either on an individual or a group.

A Sister Trope to Tampering with Food and Drink, which sometimes overlaps with it.
