I tweeted this out yesterday and I stand by this statement 100%.
If you don’t have a bottle opener on your key chain, I don’t even want to know you. Anyone who doesn’t have one of these things can’t be trusted.
I can’t think of a better way to get a first impression on someone other than checking their keys for one of these. If they have one, there’s a 95-100% chance that they’re someone worth getting to know.
Next time you meet someone for the first time, take a peek at their keys and see what there working with. They come in all shapes and sizes, but as long as it’s there, you’re good to go.
