I had a funny one - I was returning a bunch of unopened wine and I told the guy, there is one that was opened, indicating that when you see the open one please give it back to me.

He was kinda rude and I was like wtf. And then he proceeds to return all of the wine, I asked him "dude wheres the open bottle?" And he said "I thought you were returning that one too?"

Turns out in some states - they allow you to return opened bottle of wine. We laughed it off

How much do you have to return? That could be the most rewarding bottle recycling plan I've heard of. Screw your 10 cents, I want a refill.

haha, by his attitude, I'm assuming that people have abuse this policy before. I'm thinking if you return the empty bottle, they'll still take it, albeit a bit gruntled.

Mine was about 2/3 gone. Definitely beyond of the point of "hm..this wine taste funny"

Over the years I've had so many little moments like this with Costco, whether it is a friendly exchange with a gas station attendee, a door person stopping me and pointing out that I was over-charged, a service rep who couldn't find an off-brand pedialyte I purchased so they gave me a pedialyte and told me "eh yeah just don't tell anyone", it really started to make sense to me why when you mention Costco - some people would light up and say "man I LOVE Costco", when it's just a store.
