It’s a simple answer, NO! Often you will find bars giving away free glasses or will receive them at homebrew competitions, but don’t go on a mission snagging every glass you find or one day you will find yourself with so many you cannot give them away. My suggestion is to only keep or accept glasses you care about. I purged several years ago and found one person interested in the tasters, someone else wanted the steins, another wanted some particular logo glasses, and then several ended up in the recycle bin. It wasn’t difficult to cull the wheat from the chaff, but it was difficult to get rid of them. I do occasionally add another meaningful glass to the collection, but it is rare.
