I’ve been a costco member since 1988. The two things I love about the samples are:
1. They’ve actually turned us on to stuff that we buy regularly, years after first sampling.
2. I can actually get an entire meal sampling and used to do that a lot. It wasn’t really a “save money” thing. Rather, it was a convenience and variety thing. I don’t like eating at restaurants that much. and one reason is that they give you too much food.
But the downside is that they cause huge congestion, and I’d REALLY like a “no kids” rule.
They DO require parents to give the kids permission - but you know how that goes.
My favorite are the 1/4 hamburgers they give out.
That and the icecream.
People can be utterly clueless that they are blocking an entire aisle while chomping down on free food with the kids.
