yes, its tacky to leave the price tag on, if you are around tacky people though they may apricate it if you want people to know you are using the good stuff buy a tantalus and put the good stuff in it and keep it on a high shelf people will just assume thats the good stuff even if its just jack daniels, or just straight up tell them but in a subtle way, frame it like a tasting experience although that can back fire if they prefer the cheap stuff, if they prefer the cheap stuff you know not to waste the good stuff on the cretin
