When traversing the drainage pipe that leads to Barnsworth Fried Chicken II, the player can spot graffiti that reads "PAY NO POLL TAX" and "DING DONG THE WITCH IS DEAD!" A parody of the former, "PAY NO GRAVY TAX!", is also graffitied on Barnsworth Fried Chicken II's metal door. These reference slogans from opponents of former British prime minister Margaret Thatcher.

"PAY NO POLL TAX" and, by extension, "PAY NO GRAVY TAX!" reference the Community Charge, a controversial policy of the Thatcher administration that resulted in her 1990 resignation following widespread protests (it was ultimately replaced by the Council Tax three years later). Meanwhile, "DING DONG THE WITCH IS DEAD!" references a campaign by anti-Thatcherites following her death in 2013 to inflate the chart position of "Ding-Dong! The Witch Is Dead", a song from the 1939 film adaptation of The Wizard of Oz, under the pretense that the BBC would be forced to play it over the radio. The network ultimately compromised by including a brief snippet in a news report about the campaign. The presence of both references ties in with the game's setting in Northern England, where anti-Thatcherism is particularly pronounced.
