Sam is a beleaguered sandwich store clerk who is having a very bad day. Then he has a life-altering encounter with Frank - a force of nature who believes the customer is always right. Horribly, horribly right. 'Hold The Mayo' is a gruesome comedy about words that cannot be unspoken, and sandwiches that cannot be unmade. Profound philosophical questions lead to graphic consequences, all pivoting around the world's most foul condiment.
