It's not like they're complaining that their Slurpee is 99% ice or something, but if the cocktail calls for "shot of vodka, shot of vermouth, shot of gin, shot of Campari, three shots of juice, squirt of lemon" and ends up being a thimbleful of booze, that's a problem.
Thank you for asking.
Its my hobby to collect old,used and broken stuff and make it "healthy" again (if possible).
But I think there are users here they have a lot more. :-)
