Our friends ( a very old couple) go there on Friday to EAT. Not to buy anything. Just to get a free lunch. They get a shopping cart, get a drink (1 as they can refill it all they want) at the concession and head to the food isles.
I am surprised they don't bring their own plates with knife and fork. Maybe even a folding table and linen tablecloth.....
Funny part is, they are loaded with money. Guess thats why they are loaded with money.
In all seriousness, I learned to not eat lunch before going to Costco on Friday's and Saturday's unless you want to over eat.
They put out some great food for tasting.
I try to go during the week as its not as crowded. But I do enjoy the sampling.
