Although none of the items mentioned are legal, many shopfronts and restaurants will present you with these menus once you're ushered inside away from preying eyes.
For those that order, you have a sneaking suspicion that you're being watched - even before the effects kick in. Police frequently collaborate with restaurant management and bar stuff, so if you've ordered something off the menu, consume it on the premises and don't take it home with you!
The vast majority of these 'outlets' are called TV bars, meaning they show one singular series in repeat, over and over again. Family Guy is there for those who want to laugh, while those whose ribs hurts from hysterical fits of laughter of explosive diarrhea due to rampant food poisoning, tend to watch Friends instead, where there is never any danger of anyone laughing.
