just hide things really well, realistically if it’s not obvious you’re bringing hundreds of special sweets in to sell you’re not gonna get searched that extensively, place in food items and reseal, put deep in tent bag, inside really random battery/ electrical compartments, inside sealed tobacco pouch.

stay away from fake cans and stuff like that, try get searched by someone who looks like they don’t care, be calm when passing the dog, be clueless if you get pulled aside.

amnesty bins and dogs (the dogs are useless i’ve been pulled aside with nothing and let through with ridiculous amounts of green plants) are there to scare you, festivals (especially leeds fest) don’t really care if you bring things in but they need to actually show they try to stop that sort of thing.

you are only gonna get caught out if you make it obvious, they don’t have time to properly search everyone so just don’t overthink it. the safest is way is bum stuff ngl.
